Hi All,
We have been trying to test 1080p60 display on VOUT1 interface of AM5728. We are using the following setup.
AM5728 VOUT1 Port --> SDI Transmitter --> SDI Cable --> SDI Receiver
We see data corruption at the SDI receiver and it is detecting it as invalid standard. On debugging further we found out that the jitter present on the VOUT1 clock is too high.
It is around 600 picoseconds which is 2UI (User Intervals) for the 1080p60 data rate of 3Gbps. The SDI transmitter IC is thus not able to remove this jitter and hence the output is not proper.
Please find attached the jitter measurement. We have used the manual mode delay values for VOUT1 pins and are giving data at the positive edge of the clock.
Can you please help us out in finding the root cause and resolving the same.
Regards
Ayusman
