DS90UB948-Q1: Can the TI941 obtain the parameters of the blanking area that has been received?

Hi Min,

The deserializer doesn't receive any blanking from the serializer. Therefore, there are no registers available for reading the blanking being sent from the serializer.

Hi Aaron,

    The picture above shows the design of our company's TI941 coaxial solution. Is there any problem with this part?     I have reviewed your company's coaxial solution. The DOUT_N terminal requires a 47pF capacitor, but our design here uses a 100pF capacitor. Will there be any issues?

Hi Min,

The coax configuration looks correct except AC coupling caps for N signal should be 47nF or value suggested in the datasheet. You can terminate the 50Ω resistors R9411 and R9412 closer to the device. By the way, are you using external clock source or internal clock from the DSI?

Aaron

Hi Aaron,

Ok. Let's try changing it to 47nF insteaded. We use internal clock from the DSI.

Hi Min,

If you want to use the reference from DSI, you need to make sure that the register set to 0x56 = 0x02 and 0x4F = 0x80.
