Dear Sirs,

We have use DS90UB947-Q1EVM and DS90UH947-Q1. Does DS90UB947-Q1EVM can work with DS90UH948-Q1?

Should I modify any registers via Analog LaunchPAD? Because our display out from DS90UH948 is disorder.

Our H/W configuration as below:

1. One channel LVDS input from Mother board to DS90UB947-Q1EVM

2. A Dual FPD-LINKIII cable connect with DS90UH948

3. DS90UH948 dual LVDS output to panel, resolution is 1920x720.

Sincerely,

Apollo

Apollo,

what video source do you use? if using internal data pattern, you need set the registers, please refer to d/s of UB947 for details on data pattern setting.

best regards,

Steven

Hi Steven,

It's well done on our customer's board via FPD-LINK III. There are too many noise from PCLK. I have got a filter to do that.

Thanks for your reply.

Sincerely,

Apollo
