Extra SDATA_OUT on ADAU1452

Hi All,

 

I'm using SDATA_OUT3, SDATA_OUT1, SDATA_OUT0 to send data to Amplifier chips. The Amplifier chips only support I2S, so I cannot use TDM to reduce SDATA_OUT pin count.

SDATA_OUT2 is used for transferring data to a streaming module.

So I need to add a extra SDATA_OUT pin that syncs with OUT 3/1/0. Is there a way I can output a fifth SDATA channel on pin LRCLK_OUT1/MP5, or other pin ?

 

If this is not possible, can someone suggest a cost effective DAC chip with SPDIF input?

 

Best regards,

Thomas
