Hello,

I am trying to configure the CSI-2 Indirect Registers in DS90UB940-Q1.

However, I can only see field names like 'Tck Trail Value' in Register Field Descriptions Table below.

How can I get more details about all of the CSI-2 Indirect Registers?

Thanks.

Hi Sooyoung,

There is an app note that details how to program the CSI-2 registers in the 940 device. Link is below

App note: Link

Thank you for including the video timing. The incoming video has a PCLK of 1010*760*60 = 46.056MHz. If you are using four CSI-2 lanes, refer to table 3 in the app note. If you are using two CSI-2 lanes, refer to table 4.

In section 4.3, there is example code for programming the CSI-2 registers.

Best,

Jack
