Hi team.
this is brandon. we are meeting a question related to Signal communication.
Now when the DS280DF810 chip we are using is used as a BERT, we found a situation where the signal is not communicating.
In the case of the following figure, TX_7 is used as the transmitter and RX_1 is used as the receiver. There is a normal eye diagram of the sender, but the receiver cannot communicate. In this case, the communication is not started when the error code is detected, but the communication starts after a few seconds, but the error communication is indeed large. Then use TX_0 as the transmitter, and the communication is normal again. Read the rate configuration of the chip, PRBS is normal. This situation happens occasionally. I would like to ask, besides PRBS and rate, what other registers may cause communication failure?
