I just have a basic question about configuring the CS8421 ASRC chip.

A while back i bought one of these modules:

CS8421 I2S sample rate conversion module upscaling | eBay

As described by the vendor, it is preconfigured for 24/211 output. Trick is, I want to use it with a CS4397 which I'm pretty sure maxes out at 192k.

Having a bit of a brain cramp reading the datasheet. Do i need a different clock to select 192khz?
 
Did you solve your problem?
I also bought this module but for CS4399, which is 32bit.
PCB with CS8421 is pre-configured for 24-bit output.
According to dataschet and placed tables, SAOF pin change is enough
with 4.02 k ± 1% to GND I²S 24-bit date
at 8.06 k ± 1% to GND I²S 32-bit date
Has anyone tried such changes?
 
There is a datasheet for CS8421 at Mouser: http://www.mouser.com/ds/2/76/CS8421_F7-765043.pdf
It should tell you everything you need to know, or at least be a good start. Beyond that it would probably be a matter of understanding the I2S/PCM/TDM formats and interfacing to whatever to want to interface to.

Otherwise, if all that has been done and there are remaining questions or issues then maybe we could try to assist.
