Dear,
Our customer used DS90UB949+DS90UB948 for his application, and he found that the display could appear normally with STP cable, but when he changed the coaxial cable, the processor kept reading random message and report error, but the display is normal, The PCLK clock is 25Mhz. He checked that the LOCK is also high, so does the report error affect the lock signal? The IO data rate of high-speed backchannel is 5Mhz. Could you please help to analyze?
In addition, he also checked that if 948+949 worked more than two hours, and he captured the lock signal of UB948 which has jitter phenomenon. What is the reason of the jitter?
Best regards
Kailyn
