Hi TI team.

I'm from Honeywell IOT team Joey Qu , recently we are doing the MCU resiliency. so we need to create new design compatible with old design.

there is I2S port. our old design has a MCLK signal. but TI has no this HW pin, i think i could use ACLKR to do this function. is that OK? just like below diagram.

  by the way. if our old AUD port are 3.3V domain, except AUD_MCLK(1.8V). but for TI i think the same AUD share the same power domain.

considering compatible issue. whether i could use such as MCASP0 as 3.3V domain for (ACLKX/AXR0/AFSX/AXR1), and use MCASP1(ACLKR) as 1.8V? 

is there will have audio synchronization issue?

Hope your feedback, Thank you
