    Hi,

    Thank you for reaching out.

    On CC26xx devices (CC2640R2, CC2651R3, CC2642, CC2652R7, CC2674R10, etc.), the maximum I2S clock rate is 4 MHz. Assuming you want to sample 16-bit audio over I2S, you can then sample up to 128 kHz - i.e. 4 MHz / 32.

    I hope this will help,

    Best regards,
