Hi, looking at a similar setup.
Connecting a 24.576MHz clock to mcasp0_ahclkx and a 22.5792MHz to mcasp0_ahclkr.
Running a PCM1791A as slave @96 or 192kHz, and a PCM1851A slave @44.1kHz
Need some help on deciding what to use to generate those clocks.
Most basic would be to go for 2x oscillators. I've seen Abracon mems types like ASDMB-series in use but also heard someone saying that mems osc's to be avoided for audio clocks.
Option 2 would be to use a programmable clock generator like Silabs Si5351 that could output two clocks to the McAsp (with some flexibility). Though this IC will need a crystal at 25MHz so cost will be higher. (These can accept an external clock to avoid the xtal but reading the AM335x datasheet .. "Using these signals for time-critical external circuits is discouraged because of unpredictable jitter performance." I guess the 24MHz clock out is not suitable.
Also, some schematic and layout best-practices for tying the osc to mcasp&mclk inputs would be greatly appreciated.
