Part Number: DS90UB925Q-Q1

Hi,

Our customer is using DS90UB925Q-Q1. He wants to know:

1. How to configure DS90UB925Q-Q1 through I2C? Is there any example code?

2. Does DS90UB925Q-Q1 communicate with host through DIN[23:0]?

3. Could you please help check the schematic as attachment?

Thanks.

    Kevin,
    you can use ub921 to replace ub925 as they are p2p.
    for your questions:
    1. you can use local i2c master to link with ub925 via scl/sda, and set the correct idx based on d/s application request;
    2. please be careful of: a. removing dout+/- test points; avp3225 should meet SI request for high speed dff. signals. b. removing test points in power supplies pins; have good supply noise performance (enough capacitors for filtering).

    best regards,
    Steven
