DS90UB948-Q1: DS90UB948 and DS90UB949 HDMI Input Configuration

Larry Li85

Part Number: DS90UB948-Q1

Hi Team,

My customer are working for a display module (948 on their board). They want to use DS90UB949 EVM to link their 948 board with HDMI input. Could you share the basic HDMI input mode register configuration？

Looking forward to your reply.

Hello Larry,

Configuration depends on what you are trying to achieve. Can you please be more specific about what you are struggling with?

Hi Casey,

We just need a simple reference configuration to test the link from HDMI input -> DS90UB949 -> DS90UB948 -> Display. As I'm green hand and I'm not sure whihc registers should be configured during the testing.

Many thanks.

Brian,

Please consult the EVM users guides and datasheets for these parts first:

What kind of display is it? Does it have an EDID which can be read by the serializer?

Best Regards,
Casey
