DS90UB941AS-Q1: DS90UB941AS-Q1 DSI timing

941 DSI 寄存器差异.xlsx941+948.xlsx

Hi Expert,

My customer is using 941+948 in their project.

Customer is using pattern mode to do some test. External clock:LMK05318

1．Internal clk + internal timing ，OK

2．external clk + internal timing ，OK

3．external clk + external timing ，the picture shown on screen has shifted to the left.

We all know that 941 won't process the timing signal of the vedio. We has a meeting with my customer and Qualcomm.

I suggest customer to use dedicated DSI analyzer or high-speed oscilloscope with DSI analysis software. However, Qualcomm and my customer reflect that they don't have such device. I cannot find such device in China to support them.

Is there any hidden registers to help us to identify the HBP,VBP? Or help us to identify the DSI issue?

Attached is the DSI page and main page dumped from 941.

Thanks a lot to your help!

Kind Regards

Imelda
