Description

Technical Field

[0001] The present invention relates to the technical field of data transmission, and more specifically, to an LVDS receiving method and system that adaptively adjusts delay according to temperature changes. Background Art

[0002] In data transmission, LVDS is a commonly used standard protocol, such as video data transmission, ADC data transmission, etc. However, the transmission stability depends on the phase relationship between the clock and the data. Only when the phase relationship between the clock and the data is within the correct range, that is, the clock sampling edge is within the data stable range, can the data be correctly received, as Figure 1 shown; the higher the transmission rate and the higher the clock frequency, the smaller this "data stable range", and it is easily affected by external factors (such as temperature), resulting in the phase relationship between the clock and the data exceeding the "data stable range", which easily leads to data reception errors, as Figure 2 shown.

[0003] As Figure 3 shown is a commonly used LVDS transmission architecture diagram. The common transmitters include video SENSOR, ADC, or FPGA, etc., and the receiver is FPGA; the conventional LVDS receiver processing method is as Figure 4 shown. First, differential to single-ended conversion is performed, and then the data phase is adjusted, that is, the data delay is adjusted (it needs to be adjusted at high speed, generally not at low speed), so that the clock sampling edge is within the data stable range, so as to collect the correct data. Then the current clock delay parameter is fixed, and the adjustment is completed; the defect of this method is that after adjusting the clock delay at normal temperature and fixing the delay parameter, when the temperature rises, it may cause the phase relationship between the clock and the data line to change, and the original delay parameter at normal temperature is not suitable for high temperature conditions, which may lead to data acquisition errors; there is a need for an LVDS receiving method and system that can solve the above defects and adaptively adjust the delay according to temperature changes. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an LVDS receiving method that adaptively adjusts delay according to temperature changes in view of the above defects of the prior art, and also provides an LVDS receiving system that adaptively adjusts delay according to temperature changes.

[0005] The technical solution adopted by the present invention to solve its technical problems is: Construct an LVDS receiving method that adaptively adjusts delay according to temperature changes, which includes the following steps: After the system starts, the initial delay calculation module outputs delay parameters. The adjustment step size of the delay parameters is L. According to the valid data collected under different delay parameter conditions, the stable range of the delay parameters TD = TMAX – TMIN is calculated; Take the center point of the stable range TD as the delay parameter TMID of the P end of the data = (TD) / 2 + TMIN; take the leftmost value TMIN of the stable range TD as the delay parameter of the N end of the data; Output and collect the valid data at intervals of the set duration, and perform the following two steps after each collection: Compare the collected valid data with the data at the P end. If they are the same, jump to the next step. If they are different, subtract L from TMIN and then compare the collected value with the data at the P end again. If they are the same, recalculate TMAX and the delay parameter TMID of the P end of the data, update in real time and end this adjustment; Take the rightmost value TMAX of the stable range as the delay parameter of the N end of the data, compare the collected value with the data at the P end. If they are the same, jump to the previous step. If they are different, add L to TMAX and then compare the collected value with the data at the P end again. If they are the same, recalculate TMIN and the delay parameter TMID of the P end of the data, update in real time and end this adjustment.

If so, it is determined that the current delay parameter is within the stable range. If not, it is determined that the current delay parameter is within the unstable range; Find the edge of the delay parameter to obtain the stable range of the delay parameter.

[0007] In the LVDS receiving method for adaptively adjusting the delay according to temperature change described in the present invention, wherein, the step of judging whether the received data is an identification word includes: Judge whether the number of characters of the received data is the set number. If not, continue to receive. If so, judge whether each character is an identification word. If so, it is determined that the received data are all identification words. If not, it is determined that the received data are not all identification words.

Specific embodiments

[0015] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] The LVDS receiving method for adaptively adjusting the delay according to temperature changes in a preferred embodiment of the present invention, as Figure 5 shown, and referring to Figures 6 - 10 simultaneously, includes the following steps: S01: After the system starts, the initial delay calculation module outputs the delay parameter, and the adjustment step size of the delay parameter is L. According to the valid data collected under different delay parameters, calculate the stable range of the delay parameter TD = TMAX - TMIN; S02: Take the center point of the stable range TD as the delay parameter TMID of the data P terminal = (TD) / 2 + TMIN; take the leftmost value TMIN of the stable range TD as the delay parameter of the data N terminal; S03: Output and collect the valid data at intervals of a set duration, and perform the following two steps after each collection: Compare the collected valid data with the data P terminal. If they are the same, jump to the next step. If they are different, subtract L from TMIN and then compare the collected value with the data P terminal again. If they are the same, recalculate TMAX and the delay parameter TMID of the data P terminal, update in real time, and end this adjustment; Take the rightmost value TMAX of the stable range as the delay parameter of the data N terminal, compare the collected value with the data P terminal. If they are the same, jump to the previous step. If they are different, add L to TMAX and then compare the collected value with the data P terminal again. If they are the same, recalculate TMIN and the delay parameter TMID of the data P terminal, update in real time, and end this adjustment; Using the method of this application, the P terminal of the data is used as the effective channel, and the delay is set at the center of the stable range. The collected data is output. The N terminal of the data is used as the monitoring channel, and the delay is set at the outermost edge of the stable range (circulating left and right). The collected data is compared with the data collected by the P terminal of the data. If they are the same, it means that the stable range has not changed, and the delay parameter of the P terminal of the data is maintained. If they are different, it means that the stable range has changed. According to the current delay setting of the N terminal of the data, the center position of the stable range is modified, the delay of the P terminal of the data is modified, and at the same time, the edge position of the stable range is also modified. In this way, it can be ensured that the P terminal of the data is always at the center position of the stable range and the correct data is output. Even if the stable range changes, the delay of the P terminal of the data will be adjusted accordingly, without affecting the data output, ensuring that when the temperature changes, the phase relationship between the clock and the data is always within the "stable range", and the collected data is also correct, solving this industry problem encountered currently.

[0017] It should be noted that the parameter styles adopted in this application are only for illustrative purposes and are not used for limitation. They can also be changed to other identifiers; More specific operation process: 1. After the system starts, the initial delay calculation module outputs the delay parameter, which accumulates from the minimum delay parameter 0 to the maximum MAX; the step length is set to L. According to the data collected under different delay parameter conditions, the stable range of the delay parameter TD = TMAX – TMIN is calculated. Refer to Figure 6 。

[0018] The above belongs to the traditional LVDS receive delay adjustment. The specific method is that the sending end sends the identification word. Each time the receiving end adjusts the delay, it judges whether the received data is the identification word. If it is, it means that the current delay parameter is within the stable range. If not, it means that the current delay parameter is within the unstable range. In this way, the outermost edge of the delay parameter can be found, and the stable range of the delay parameter can be obtained. Note: Each time the delay parameter is adjusted, a period of time needs to be waited. For example, if it is set to wait for 1000 data to be received, then when 1000 received data are all identification words, it is considered that the current delay parameter belongs to the stable range, otherwise it is considered to belong to the unstable range.

[0019] 2. Take the center point of the stable range as the delay parameter of the P terminal TMID = (TD) / 2 + TMIN; The P terminal is used as the effective channel, and its delay parameter TMID should always be at the center point of the stable range. If the temperature changes, resulting in changes in TMIN and TMAX, then TMID should also change accordingly.

[0020] 3. Take the leftmost value TMIN of the stable range as the delay parameter of the N terminal, and compare the collected value with the P terminal.

[0021] Under normal conditions, the delay parameter at the P end is at the center position, and the delay parameter at the N end is at the far left. Then their phase relationship is as Figure 7 shown. In this case, since both the P end and the N end are within the stable range, the collected data is also the same. In this case, jump to step 4 for the right-side judgment.

[0022] If due to temperature change, the data line shifts to the right relative to the clock line by a certain amount, as Figure 8 shown. The P end is still within the stable range, and the output sampled data is still correct. However, the N end has exceeded the sampling range, and the collected data is already incorrect and definitely different from the P end. At this time, use TMIN - L as the delay parameter of the N end and shift the N end to the left, so that the N end is again within the stable range. At this time, the collected data is compared with the P end and is the same again. However, at this time, the delay parameter TMIN of the N end has changed to TMIN = TMIN - L. In this case, it is necessary to recalculate TMAX and the delay parameter TMID of the P end and update them in real time.

[0023] Note: Each time the delay parameter is adjusted, it is necessary to wait for a period of time. For example, if it is set to wait for 1000 data to be received, then only when the 1000 received data are the same as the P end after comparison is the comparison result considered the same; otherwise, it is different.

[0024] 4. Take the rightmost value TMAX of the stable range as the delay parameter of the N end and compare the collected value with the P end.

[0025] Under normal conditions, the delay parameter at the P end is at the center position, and the delay parameter at the N end is at the far right. Then their phase relationship is as Figure 9 shown. In this case, since both the P end and the N end are within the stable range, the collected data is also the same. In this case, jump to step 3 for the left-side judgment.

[0026] If due to temperature change, the data line shifts to the left relative to the clock line by a certain amount, as Figure 10 shown. The P end is still within the stable range, and the output sampled data is still correct. However, the N end has exceeded the sampling range, and the collected data is already incorrect and definitely different from the P end. At this time, use TMAX + L as the delay parameter of the N end and shift the N end to the right, so that the N end is again within the stable range. At this time, the collected data is compared with the P end and is the same again. However, at this time, the delay parameter TMAX of the N end has changed to TMAX = TMAX + L. In this case, it is necessary to recalculate TMIN and the delay parameter TMID of the P end and update them in real time.

[0027] Note: Each time the delay parameter is adjusted, a period of time must be waited. For example, if it is set to wait for receiving 1000 data, only when the 1000 data received are the same as those compared at the P end, the comparison result is considered the same; otherwise, it is different.

[0028] Illustrate with examples Suppose the current transmission speed is 1000M, then the clock period is 1000ps, the delay parameter adjustment range is 0 - 1500ps, and the step L = 50ps 1. After the system starts, the initial delay calculation module calculates that the stable range of the delay parameter is TMAX = 500ps, TMIN = 150ps, TD = TMAX - TMIN = 350ps; 2. Take the center point of the stable range as the delay parameter of the P end; TMID = (TD) / 2 + TMIN = 350 / 2 + 150 = 325ps. Since the step is 50, we can choose TMID = 300ps for the nearest value; 3. TMIN = 150ps is used as the delay parameter of the N end, and the collected value is compared with the P end; If they are the same, jump to step 4. If they are different, subtract L, and compare the collected value with the P end when TMIN = 100. If the comparison is different when TMIN = 150ps and the comparison is the same when TMIN = 100ps, it means that the left boundary has become 100, then adjust: TMIN = 100ps, TMAX = 450ps, TMID = (TD) / 2 + TMIN = 350 / 2 + 100 = 275ps; 4. TMAX = 500 is used as the delay parameter of the N end, and the collected value is compared with the P end.

[0029] If they are the same, jump to step 3.

[0030] If they are different, continue to add L, and compare the collected value with the P end when TMAX = 550.

[0031] If the comparison is different when TMAX = 500ps and the comparison is the same when TMAX = 550ps, it means that the right boundary has become 550, then adjust: TMAX = 550ps, TMIN = 200ps, TMID = (TD) / 2 + TMIN = 350 / 2 + 200 = 375ps.

[0032] An LVDS receiving system that adaptively adjusts the delay according to temperature changes, as Figure 11 shown, the system includes a single - ended to differential converter 1, a first serial - to - parallel conversion unit 2, and a delay processing module; A single - ended to differential converter 1 is used to integrate the clock P - end signal and the clock N - end signal into clock data and then input it into the serial - to - parallel conversion unit; The first serial - to - parallel conversion unit 2 receives the clock data and the data on the data P - end and integrates them into the parallel data of the valid channel. The parallel data of the valid channel is output as valid data; The delay processing module is used to execute the LVDS receiving method for adaptively adjusting the delay according to the temperature change as described above.

[0033] In the system applying this application, the data P - end is used as the valid channel, and the delay is set at the center of the stable range. The collected data is output. The data N - end is used as the monitoring channel, and the delay is set at the outermost edge of the stable range (circulating left and right). The collected data is compared with the data collected by the data P - end. If they are the same, it means that the stable range has not changed, and the delay parameter of the data P - end remains unchanged. If they are different, it means that the stable range has changed. According to the current delay setting of the data N - end, the center position of the stable range is modified, the delay of the data P - end is modified, and at the same time, the edge position of the stable range is also modified. In this way, it can be ensured that the data P - end is always at the center position of the stable range and outputs the correct data. Even if the stable range changes, the delay of the data P - end will be adjusted accordingly, without affecting the data output, ensuring that when the temperature changes, the phase relationship between the clock and the data is always within the "stable range", and the collected data is also correct, solving this industry problem encountered currently.
