  • Stabilization Of Oscillater, Synchronisation, Frequency Synthesizers (AREA)

Abstract

A method and apparatus for recovering the time base of signals which change at periodic intervals is disclosed. The apparatus comprises gated voltage controlled oscillators (GVCO) that are alternated or exchanged, to reduce phase and frequency deviations in the recovered time base signal, such as the deviations induced by inherent GVCO differences. Each GVCO is stabilized by a respective phase locked loop. The respective GVCOs are gated only in response to a chosen polarity transition in the input signal, to make the circuit more tolerant of waveform distortions. More than two GVCOs may be used to provide improved frequency drift resistance. The circuit uses resynchronization control signals, such as the time slot signal in synchronous switching systems, to indicate resynchronization or reassignment the GVCO in gaps in the data transmission. Automatic reassignment is insured when there are periods of non-transitioning data that last longer then the stability of the GVCOs to prevent frequency drift in the recovered clock.

Description of the invention: (1) Field of the present invention The present invention relates to a circuit for providing a synchronization signal having a defined phase relationship with respect to an input signal, for example, a recovered clock. More particularly, the present invention relates to a signal processing circuit for providing these signals. Discussion of related technologies In a multi-gigabit optical data network, an efficient receiver must be able to achieve bit-level synchronization within 20 billionths of a second and maintain synchronization at 500ths of a billionth of a second. , And then in some applications can be synchronized with another signal source in the same short time. At these speeds, over state-of-the-art digital technology is available, oversampling is not a practical way to ensure pulse hold accuracy. A clock recovery circuit is necessary. U.S. Patent No. 5,237,290 (> 290 patent) has published a clock recovery circuit using a matching variable frequency voltage controlled oscillator (VC0s). The contents of the / 290 patent are hereby incorporated by reference. Printed by the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs. In particular, the phase-locked loop-back clock recovery circuit shown in Figure 8 of the / 2 9 Q patent is based on most oscillator circuits that may use integrated circuit production technology. The precise response of the electrical characteristics works. Because these circuits are only "indirectly adjusted", the circuit's oscillator operates at a slightly different frequency. The frequency difference between the oscillators will be emphasized, so that when the input signal is in the unbroken string of 1 or 0 without being transformed, it is generated between the recovered clock and the input data Frequency drift and possible misalignment. The clock drifts when the input signal is restored without change for a long time. The paper size is in accordance with Chinese National Standard (匸 吣) 8 4 Specifications (210/297 mm)-4 Printed by the Consumer Cooperative of the Central Prototype Bureau of the Ministry of Economic Affairs A7 B7 5 2. Description of the invention (2) When shifting, the citrus bit of the recovered clock will be shifted when re-transformed, thus causing an error until the oscillator can be synchronized again. Another possible source of error is caused by distortion and loss of data input signals. The main cause of the failure is that the reactance of the transmission medium and similar eddy current effects distort the analog data signal. Due to the uncertainty caused by the digitization threshold, the effective width of the detected digital data pulse will be greatly reduced. These distorted data signals also cause problems in the > 290 circuit. A missed data input will cause subsequent clock signals to be lost, making its pulse width very narrow. When these pulse widths become too narrow, they cannot be reliably used in data recovery circuits. SUMMARY OF THE INVENTION The present invention generates a synchronization signal for sampling an input data signal, and overcomes the limitation of the minimum operation cycle and transition density of the input data stream required by the prior art. The present invention uses a plurality of oscillating signals, each adjusted to a reference periodic signal. An oscillating signal at any time is connected to the synchronization signal. As a result of a selected transition of the input data, a new oscillating signal is sent out, phase-aligned with the input data pulse and connected to the synchronization signal. When oscillating signals are not connected to the output, they can be suspended or resynchronized with a reference pulse signal. This will produce a reliable, tolerant, synchronized signal. This synchronized signal has a defined phase relationship with the input signal and is used to recover the input. The paper size applies the Chinese National Standard (CNS) Λ4 specification (210X297 mm)

Description of the invention (3) Data bits received on the signal. The present invention is very useful when the digitized partial code data must be recovered without changing the data clock. In particular, it is quite suitable for regenerating unstable transition data. An embodiment of the present invention assumes that the input data stream includes a period of action, during which valid data is transmitted, which is hereinafter referred to as the action data, and is separated by a standby period in the middle, during which no valid data is transmitted, called a gap. These gap times are not used to synchronize the frequency of a reference signal that synchronizes the oscillating signal with a frequency that is fairly close to the known and input data signals. The oscillating signal must be stably kept in synchronization with the frequency of the input data signal for a period of time equal to or greater than the maximum action period. The length of the partial gap known by the prior art must be sufficient to enable the oscillating signal to be stepped from the reference signal. In this embodiment, only two oscillation signals are required. During the gap, both oscillating signals are synchronized with the frequency of a reference signal. During the use of data, the two oscillating cels will be sent out alternately in response to a transition in an input signal with a known polarity and connected to a synchronization signal. During these cycles, the frequency of these oscillating signals is maintained using the bias signal 讯 determined during the previous gap. The present invention is very suitable for systems where data gaps are intentionally or statistically located. These systems include synchronous switching equipment that can completely locate positioning data and gaps in a time-zoned manner. Relative to the time lock gap required for synchronously switching devices, the data network system can statistically provide a determined minimum gap in a data stream.

Order the A7 B7 printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs. 5. Description of the invention. (4) Frequency, distribution and period. These systems provide a code or some other signal that can initiate a transmission monitoring signal indicating when such a statistically located gap will occur, such as a data header block or a data end block. For example, satellite data link communication equipment and central control room frame relays or ATM switching equipment systems require high stability. A gap that reflects a periodic signal and is located deterministically in a data flow center must be used to ensure the minimum demand for the gap. Period and frequency. The data set mode communication link used for transmitting and receiving data frames in optical networks and switches can address the gaps in each frame, thus ensuring correct synchronization based on each frame. In another preferred embodiment, two oscillating signals are alternately provided to the output, while the third can be resynchronized by being executed under the control of its phase locked loop. An additional oscillating signal will be provided so that there is always an oscillating signal operating in resynchronization mode. At a known time, the re-synchronized oscillating signal is reset to alternately generate an output synchronization signal, and an oscillating signal originally used to generate the synchronization signal is reset to re-synchronize. These new settings will be systematically implemented for all three oscillating signals, allowing each to alternately resynchronize before generating significant drift relative to the reference signal. 0

Description of the invention (5) or T 3 , Or a system that cannot tolerate the cost of the gap, it is quite advantageous. This preferred embodiment relies on a positive or negative transition of the input data, rather than two directions in parallel, because it is known that the input data signal cycle is lacking. Symmetry is a cause of data processing errors. The phase is synchronized using a specific change in the input signal and the frequency is synchronized to a stable reference. The thyristor voltage-controlled oscillator provides a fixed regenerated clock signal, making the serial communication signal It is possible to quickly synchronize bits. The invention can achieve even a small synchronization in the data stream, so that it can be used in data set mode or continuous point-to-point applications. The present invention may require the high-speed clock used in its main clock recovery method for oversampling, so that the circuit can be designed to maximize the data transfer rate by any known technique. The present invention provides a robust clock recovery circuit, which is relatively less susceptible to data errors caused by data loss due to data signal loss and drift.

Take a detailed description of the embodiment. In Figure 8 of the Consumer Cooperatives printed by the Central Standards Bureau of the Ministry of Economic Affairs, such as > 2 0 0 patents, among the clock recovery circuit 10 in FIG. 1, the first and second Each GVC01 1, 12 receives a very complete data signal 1 4 a appearing at the input terminal 14 through the action of the converter 16. After they are reversed in polarity by converter 16, the first GVC0 1 1 will be activated by the transition of signal 1 4 a to the negative direction: and the second GVC01 2 will be negative by the data signal 1 4 a The change of direction starts its effect. The frequency of the first and second GVC01 1, 1 2 utilizes, for example, a third control circuit including a phase detector 'phase lock loop element connected to a reference signal " f " A matching GVC 0 1 8 was adjusted. The respective GVCQ signals 1 1 a and 12 a are output by the NOR gate element 17 in the form of a synchronized signal 17 a. The original technology clock recovery circuit 10 in Figure 1 has its stupidity, but this paper size applies the Chinese National Standard (CNS) Λ4 specification (210X 297 mm) —9 _ A7 B7 V. Description of the invention (7 ) Isn't it perfectly fine. Because GVCOs 11 and 12 are activated by the transition between the digital 1 and 0 data frames, when the unbroken half-columns of the digital 1 or 0 occur, the precise frequency of the respective activated GVCO becomes very important. The frequencies of the GVCOs 1 1 and 12 that are activated alternately are not based on their actual, the respective frequencies are adjusted, but on the frequency of a control circuit GVC 0 18. This circuit design assumes that GVCOs 1 1, 1 2, and 18 are very similar, so they can operate with negligible frequency differences from each other if they are controlled by the same signal. However, if a sufficiently long unbroken half-column of 1 or 0 digits occurs, the three GVC 0 s will be different and the frequency difference will cause G V C 0 s to drift. When the transition occurs again in the data signal, it will cause a data error in the receiver using the recovered clock 0. The problem of signal waveform loss in this prior art circuit 10 is even more serious. For example, in Fig. 2, an 8-clock clock signal S 1 and a digital data signal 5 2 with the same clock cycle, t " are generated when the signal is transmitted in a known network. Distort the missing signal symmetrically " SA 〃. Figure 2 also shows the time threshold when a receiving device detects a transition in the input signal used by the device to generate the digitized input signal SD. Digitization of the front and back green of the missing data pulse results in digitization. The original pulse width of the input signal SD relative to the signal S 2, t " a relatively narrow pulse width a w ".

Description of Invention (8). Processing with N 0 R gate element N 〇 R produces a serious problem, that is, the clock is not a complete clock width, and the pulse width is " r '. If the small pulse element 17 applies a logical signal 1 7 a to the signals 1 l a and 1 2 a. The generated signal 1 7 a has a strict signal 1 4 a. The first / this small pulse has a valid clock. Therefore, the width pulse that is synchronized with the rate will synchronize the output frequency signals of the 1 2 0 1 1 0 0 level signal. Electricity is regarded as the clock of a 50% duty cycle. A valid clock cycle ae 〃. These small pulses, r 〃 have a period 'e 〃 significantly longer than the normal data clock period' t " the short receiver must be able to operate faster than the frequency of the data clock so that these missing signals are significantly Effective frequency with shorter clock width. Theoretically, the time generated by a digitized data pulse with a width of 50% of t " with the actual clock period of exactly the data effectively has one. Pulse width, and an infinitely fast output clock. 3 shows a high-level block diagram of a multiple G.V C 0 clock recovery system according to the present invention. The circuit 100 receives data input together with a reference clock locally generated by the local clock generator. The output of the electric signal is a synchronized signal with a defined phase relationship with the input data. By generating a normalized signal that is synchronized in phase with the input data, a data processing circuit can use the synchronized output signal from the circuit to define the data on the received input data signal. To eliminate instability, the data processing must also receive a reference clock or alternatively have its own internal clock generator circuit. Road 1 0 0 contains multiple voltage-controlled oscillator blocks 1 1 〇 and notes for reading and reading.

Invention Description (9) Ϊ · 1 1 There cannot be various embodiments, each dealing with two or more oscillator circuits. Each voltage-controlled oscillator includes an output enable circuit controlled by the OUTPUT — εν signal, enabling the output to be selectively enabled or disabled. Each voltage-controlled oscillator can respond to the V C 0 -εν input signal to be selectively activated for execution or thyristor, and when activated, the phase of each oscillator will be aligned with the activation signal. Therefore, the oscillators in these blocks are called thyristor voltage controlled oscillators GV c 0 S. The oscillators in each oscillator block are called thyristor voltage controlled oscillators (GVCOs). Each oscillator block also includes an synchronization circuit, such as a phase locked loop, that synchronizes the frequency of the oscillator with a reference clock input signal R E F — C L K. When the SYNC_CE signal is asserted, the oscillator block will be set to synchronization mode. The circuit 101 controls all activation signals sent to all GVCOs. Circuit 101 controls the GVCOs so that any time a valid data is received on the input signal, a GVCO will provide a VCO__ which is used to generate the DATA — CLOCK output signal of the circuit 1 0__ Printed by the Staff Consumer Cooperative of the Central Standards Bureau of the Ministry of Economy Signal. The circuit 1 00 must also switch the GVC 0 that provides the VCO — OUT signal used to generate DATA — C LOCK to avoid GUCO drift. Each time the GVCO s is switched and the activation signal responds to the transition of the input signal is declared and de-asserted, the phase of the activated GVCO will be aligned with the input signal. In addition, the circuit 101 must frequently synchronize the frequency of each GVCO with the reference clock signal to prevent the frequency shift of G V C 0 from exceeding an allowable range.

Description of the invention (10) The output of GVC 0 s is combined into a single data output clock in circuit 120. Circuit 1 2 0 can also be selectively deactivated via the OUT_EN signal generated by circuit 1 0 1. If all GVC 0 s is resynchronized to determine that glitches or incorrect synchronization signals have not been output on the DATA — C LOCK signal, then this function has its potential necessity. Circuit 1 3 0 can be a variety of different data processing circuits One of them. Common examples include a data parallelization circuit, a series channel repeater, a continuous periodic clock signal generator for discontinuous signal sources, etc. Circuit 1 3 0 Receive circuit 1 0 The DATA_C LOCK output signal of 0 is used to define the data bits on the input signal. Depending on the system requirements, the circuit 130 may also need to receive a local reference clock signal. The invention is particularly suitable for generating a data The clock in order to recover its data by an unstable transmission signal. This is represented by the destabilizing data parallelization circuit of Fig. 5. In a specific embodiment, it is also very suitable for a continuous clock where A non-continuous or a large number of clock source generation system. The present invention can perform this function as long as the input signal receives a large number of clock sources, and the synchronized output signal will generate a continuous clock.

A polarity selector 36 is also provided in this embodiment. The polarity selector controlled by the 'P 0 L_S E L " input connects the signal 1 4 a or its reverse 1 6 a to the bi-stable positive Inverter 3 4. When the loss of the transmitted signal is quite asymmetric, the polarity reversal of the data input signal 14a will help. Specifically, when the polarity is selected so that the leading edge of the short duty cycle pulse starts G V C 0 s, the circuit performance will be improved. The frequency of each G V C 0 is synchronized with each phase lock loop (P L L) 4 1, 4 2 indicated by a dotted line.

When the function data appears on signal 14a and signal 5 4a is undeclared, the start character detector 65 will start searching for the next matching start character pattern. Since the output 50 a of circuit 50 is deactivated during the gap in the input data, and it is not restored until a new starting character pattern is found in the input data stream, the output of circuit 50 contains only valid data 0 Using Multiple GVCOs FIG. 6 shows another preferred embodiment of the present invention, a circuit 70, in which three GVCs 3 1, 3 2, 3 3 provide synchronization signals.

Since two GVC 0 s must provide synchronization pulses when receiving the action data, this embodiment provides an additional GVCO, so that any two GV C 0 can be re-enabled when the other two GV C 0 s provide synchronization signals. Synchronization. The thyristor outputs Ag, Bg, and Cg of the GVCO can be adjusted by using their respective corresponding P L L 4 1, 4 2, and 4 3. The output of each G V C 0 is activated by an A N D gate element 7 4, 76 and 78 under the control of the circuit 80. Each GVCOE — the input is driven by a logic circuit 8 1, 8 2, 8 3. Logic circuits 8 1, 8 2 and 8 3 select one of the following three operating modes for their respective GVCOs for the E-GVC 0 start signal; the function is activated at all times, when the signal 3 4 a is low, when the signal 3 Starts when 4b is low. Circuit 80 generates control signals EN__POS and EN — NEG. In FIG. 6, three sets of control signals are marked as EN_POSa, EN_NEGa of the control circuit 81, EN_POS, EN_NEGb of the control circuit 82, and EN_POS, EN_NEGc of the control circuit 82. The three start resynchronization signals are labeled EN_SYNCa, EN_SYNCb, and EN_SYNCc for GVCOs 3 1, 3 2, and 3 3 respectively. Circuit 80 generates the start resynchronization signal EN — SYNC that controls each PLLs.

Description of the invention (l7) The signal will be issued by PLLS. Perform a phase comparison between the output of their corresponding GVCO and the periodic reference signal 4 4 a. When the EN_SYNC signal is low, the PLLs will be deactivated and the frequency control output signal F of the PLL will be maintained at the original state when the EN_SYNC signal is high. When the EN_SYNC signal changes from low to high, start their internal phase comparators using methods and techniques known in the prior art in order to eliminate the initial phase difference between the output of the GVCO and the reference signal 4 4 a. For PLL s is advantageous. This allows the entire synchronization cycle to be used to adjust the frequency of the GVCO, rather than regaining phase. The signals 3 4 a and 3 4 b are the outputs of the flip-flop 34 and are always complementary. The flip-flop 34 is provided with a clock signal by the input signal 1 4 a and its function is to change the state of the signals 3 4 a and 3 4 b alternately each time the signal 14a changes in the forward direction. At any time when the circuit 70 is operating, the control circuit 80 selects a pair of GVCOs to be called GVCO s 'X " and' and sets the output of the corresponding GVCO s to activate the control signal 0E to be high and Start their output. In Figure 6, the three output start-up circuits corresponding to GVCOs 3 1 '3 2 and 3 3 are labeled as 0Ea, OEb, and 0Ec °. The third GVCO will be referred to as GVCO in circuit 8. Under the control of 0, the corresponding output start control signal is set to low, and its output is deactivated. At the same time, the circuit 80 selects the operating mode used by the E_ inputs of all three GVCOs. By setting the corresponding EN — P 0 S and EN — NE G signals of G V C Ο 'Z 〃 to be low, they are placed in a state of being activated at all times.

During these periods—each time the GVCO is set, the paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) —21 Please read the notes and write this page A 7 B7 V. Description of the invention (19) The bias signal 値, which is allowed to be synchronized with the reference frequency for a unit disconnection from the reference frequency, is maintained. Alternate / Reset The embodiment in FIG. 6 operates by resetting those GV C 0 s symmetrically, X " and '", whichever is' Z ". The resetting controlled by the control circuit 80 must meet two requirements: each of the three GVC 0s must be set to " z " GVC 0 before its GVC 0 drift relative to the reference periodic signal exceeds an allowable amount To enable it to resynchronize, the GVCO must be provided with sufficient time for synchronization before the next reset. One of the well-known effects of the original technology printed by the staff of the Central Standards Bureau's Consumer Cooperatives in the Ministry of Economics is that very stable oscillators can tolerate considerable time to drift; however, resynchronization of these same oscillators usually also requires considerable time time. On the other hand, low-stability oscillators can be resynchronized quickly, but they also shift sources after a short period of time. Choosing the required oscillator stability and the corresponding reset time interval is a standard engineering optimization operation, which differs depending on the technology and application, and anyone familiar with the technology will understand. The simplest reset strategy is to periodically switch all three GVCOs and set each one in turn as a GVCO. Other reset modes, such as virtual and random, can also be used as long as they meet the above requirements. Embodiments with more than three G V Cos can get more reset modes. This paper size applies the Chinese National Standard (CNS) Λ4 specification (2ΐ〇χ 297mm) -22 Α7 Β7 V. Description of the invention (20) The preferred embodiment of the circuit in Figure 6 uses an external clock reference signal 4 4 a Establishes a timing reference for resetting and performs an alternate reset. Inside the circuit 80, the reference signal 4a is divided downward to generate a periodic reset clock signal at the reset frequency. The length of the clock cycle must be sufficient to allow a GV C 0 to be resynchronized as a reference periodic signal, and it must be short enough to allow each GV C 0 to perform a resynchronization operation before the drift exceeds the allowable threshold. Each time the reset clock changes from low to high, the circuit monitoring the status of the input signal Q — connected to the signal 3 4 b in the circuit 7 0 will start a reset sequencer, and a The pause counter will be started to count a predetermined number of pulses on the signal 4 4 a. The reset sequencer knows which GVCOs perform the functions of " X " and 〃 and that a GV C 0 is a function of Z 〃. The next GVC0 to be resynchronized is called the target GVC0. Circuit 8 0 also knows that or, the next time GVC0 is the target GVC0 and will become the next GVC 0. The reset sequencer waits until the target GV c0 is activated and then waits for the next transition of the signal 3 4 b, indicating that the target GVC0 is deactivated. When 3 4 b changes, reset the setting sequencer to set the function of the target GVC0, whether it is' " X " or '' is currently GVC0 of Z, GVC0, and the setting function is the target GV C. When performing this reset, the third GV C 0 also provides a synchronization signal. When the reset is complete, the 'pause counter will be started and the reset sequencer will be placed in a state waiting for the next low-to-high transition of the reset clock. This paper size applies to Chinese National Standard (CNS) Λ4 specification (210X 297 mm) —23-(Please read the notes on the back first and fill in this page) Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs ... ---- --Order ------- unM, ---- ^ --- ____B7 V. Description of the invention (21) Because the correct operation of resetting the sequencer is based on the signal that is derived from the input signal 1 4 a 3 For the 4 b transition, a mechanism must be provided so that the circuit can function correctly even if a longer data gap exists on the input. If this is not done, the long gaps in the inputs will be delayed for resetting, causing GVC 0 s to drift beyond their allowable threshold. When the data is restarted, the GVCOs will wait until all three G V Cos are synchronized before being able to provide a synchronization signal at the correct frequency. To overcome this potential problem, the circuit 80 has a pause counter so that when the counter reaches a predetermined threshold, the reset sequencer will start a reset operation regardless of the state of the signal 3 4 a. If the input signal actually contains valid data without any transitions, this may cause a unit error. Therefore, if any bit error can be tolerated, a certain transition density must be stored in the input data. Printed by the Employees' Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs Finally, any embodiment can operate in a mode in which a single oscillator provides a synchronized signal and one or more oscillators are synchronized. This oscillator will provide the synchronization signal for a period of time so that its phase will not drift by more than a permissible phase relative to the input signal before another oscillator is started to provide the synchronization signal. Switching of the oscillator is similarly restricted as discussed in the foregoing embodiments. Please note that the phases of the oscillators are aligned with the input signal when they are activated. Those skilled in the art will appreciate that various changes and modifications to the published device are possible within the spirit and scope of the invention.
