DS90UB960-Q1: Could we use ADAS SERDES to transmit I2S audio signal

Part Number: DS90UB960-Q1

Hi team,

I would like to ask that could our ADAS serdes support transmit I2S audio signal? Customer is using 960 and the SER is 935 or 953. Could we use GPIO to transmit and should we use SER's GPIO one-to-one correspondence to DES's GPIO? (I know in IVI FPDLINK III serdes should follow this rule, not sure about FPDLINK III and IV ADAS serdes).

What is the limitation of using GPIO to transmit audio signal like I2S? Is that the sampling frequency?

Thank you!
