PCM1861: Requirements for sampling rate 192khz

Part Number: PCM1861

Hi TI experts,

Customer plan to design Audio ADC for supporting sampling frequency 192khz. they choose using PCM1861.

Main controller can't support 49.152Mhz to master clock of PCM1861.

I checked that external clock of X-TAL is max 35Mhz. Can I use external OSC as CMOS MCLK?

They try to use external 49.152Mhz OSC. is it possible? If yes, How do we connect the external OSC? (XO, XI, SCKI pin)

Please check it.

Thank you.

Downey Kim.
