DS90UB948-Q1: DS90UB948-Q1 schematic design check

Dear team,

The attachment is a schematic diagram of the application of DS90UB948-Q1 Single coaxial signal input, video resolution of 1920 * 1080. Dual LVDS output Please help check if the configuration in the schematic is correct There are two other questions: First, in coaxial signal input, does GND need to add TVS, and if so, at which position? Secondly, regarding BISTEN and BISTEC, if they are not connected to the MCU, can they be configured according to the schematic diagram

Best,

Jim

Hi Esther,

In coaxial signal input, does GND need to add TVS, and if so, at which position?

Hi Jim,

You do not need to place any TVS diodes on the RIN0- traces when using coaxial. You would only need to place TVS diodes on the RIN0+ trace in this case, close to the connector like indicated in your schematic.

Esther
