DS90UB947-Q1: Remote slave I2C communication

Frank QIN

Hi Team,

My customer would like to use DS90UB947 remote slave, may I know which port is for the I2C communication? D0 or D1? If I would like to change the port, how should I do?

I didn't find such introduction in datasheet.

Thanks

Hi Frank,

Apologize if I don't understood your question. The UB947 has a I2C that you connect to via SoC. Do you mean that you want to communicate the I2C to the deserializer? In order to communicate from the SoC via deserializer for example to the MCU, you would need to fill out the slave alias ID. This can be routed to single or dual port FPD-Link. If you want to change the port, I think it is 0x1E register.

Aaron,

Yes, communicate with deserializer. It routed dual port FPDLink and they would like to figure it our because the ser and des are separate in two boxes made by two team.

Thanks for your answer, I'm looking for the register to change port.
