DS90UA101-Q1: TDM + I2C SerDes Solution (2m cable)

Hi Team,

My customer would like to use SerDes solution to transmit the TDM signal + I2C signal. I find DS90UA101-Q1 in website. Do you have any other better solution can suggest? Thank you.

Transmission length = 2meter

Hello Roy,

This is the most applicable solution we have in our portfolio for transmitting just I2S and I2C. Is there any issue with this part or can it meet the customer's requirements?

Best Regards,

Casey

Hi Casey,

Thanks for information.

We want to check if we can use independent CLK to SCK pin(DS90UA101-Q1) to send I2C and GPIO command via audio link when audio signal is not operating.(no BCK)

Hello Roy,

When there is no SCK or BCK, then the device automatically switches over to internal clock to drive the link:

So if you just want to transmit GPIO and I2C you can do this without any clock input to the device.

Casey
