DS90UB941AS-Q1: DS90UB941AS-Q1 Schematic review request

Part Number: DS90UB941AS-Q1

The customer is using DS90UB941AS-Q1 for product design. I compared the customer schematic with SNLU241A and found no abnormalities. I am not very familiar with DS90UB941AS-Q1. Can you help to check it again?

Hi Lysny,

In this case, there should be no problem with external osc, no dsi, coax. refclk 0 and 1 have no input., right?
Focus on the confirmation of REFCLK0/1,Use DSI CLK, leave REFCLK0/1 floating, is there a problem if there is no input?

Thanks.

Hi Alon,

When using the DSI clock, please set the CLOCK value = 1 for continuous.

Thanks,
