Part Number: PCM1754-Q1
Other Parts Discussed in Thread: PCM1754

Hi,

We are using PCM1754 for Audio application.

I2S SCLK is set to 18.432 MHz

I2S BCLK is set to 768 KHz

and

I2S FS is set to 24 KHz

in datasheet Table 1. System Clock Rates for Common Audio Sampling Frequencies, 24 KHz sampling frequency is not mentioned.

Could you please let us know whether 24 KHz is supported or not?

Thanks for your time and support.

Regards,
Viswanath

Viswanth, this part can support sampling frequencies between 5KHz to 200KHz, however you need to use a system clk freq that is listed in the data sheet as specific multiples of Fs. So SCK=768x24KHZ=18.432M should be ok.
