DS90UB941AS-Q1: layout question

Sherry Liang

Part Number: DS90UB941AS-Q1


Dear team,

Currently my customer is designing the layout of 941. 941 will be connect to two 948, and it is in independent mode. Each screen is 1280*720@60fps.

We know the PCB trace of D0/D1/D2/D3 should be as short as possible, but the trace will be limited due to other many devices' position. So I want to know what  the longest trace of MIPI that our chip can tolerate is. Smaller than 10cm?

Thanks & Best Regards,

Sherry

    Hi Sherry,

    It depends on the layout and the board material that you are using. You will have to do the high speed analysis and use the DSI requirements in the datasheets electrical Characteristics table. I have seen systems with 10cm DSI lines work fine.
