Hello,
Please do not post any confidential schematics on E2E since this is a public forum. To get optimal performance in the system, following proper signal integrity techniques and board/layout guidelines is important. Also the clock quality and power supply levels/ripple needs to be closely monitored as that can affect the margin in the system.

please be careful of the video format, and the VS/HS polarity in your case. the link between UR905 and UR910 can run automatically in most cases with hardware pin strop setting.

best regards,
Steven

Hi Steven,
Could you please double check whether TI can provide driver software code for DS90UR910.
Thanks a lot

UR910 can work in most cases with default setting, TI does not provide driver for it.
