DS90UB935-Q1: Poc

Part Number: DS90UB935-Q1

Hi team，

1. For DS90UB935-Q1, how to quantify the performance of the FPD-LINK signal at POC. What are the key indicators? What instruments are used to test? How can ensure the data is stable and reliable and how to test the reception rate? Do we have the application note for the above questions to provide to the customers?

2. Could you please help review the schematic?

Thank you in advance.

Regards,

Ivy

    Hi Ivy,

    The schematics look good.

    The most important PoC network design considerations is that the network must be able to cover the back channel all the way to the forward channel of the link. It also needs to support the current you're trying to pass through.

    You also need to make sure the PCB including PoC can meet the channel insertion and return loss requirements (this is usually stated in the deserializer datasheet).

    Best,
