sampling rate selection in PCM9211

Other Parts Discussed in Thread: PCM9211, MSP430F5325, SRC4190

Hello All,
According to "Table 3. ADC Clock Requirements" on datasheet of PCM9211 , ADC sampling rate can be switched into 44.1Khz, 48Khz, 88.1Khz, 96Khz.

but by setting registers 31h, 33h and 42h , i didn't find any way to set sampling rate on 44.1KHz.
using crystal oscillator of 24.576MHz and MSP430F5325 as control unit.

I need all 3 sampling rate availability with my device.
Any suggestions or help would be welcome and appreciated.

Thanks and regards:-

Hi Sonu,

In order to get the different sample rates you must provide one of the supported clock frequencies.

Hello Sir,

Thanks for the suggestion :)

M very new in audio applications will you please elaborate, how to provide supported clock frequency as it can be pre scaled internally for 48KHz and 96KHz sampling rate using crystal of 24.576Mhz,
i need 44.1KHz also with above.

Suggest me some chips or ways which can fulfill the requirement and how to make that to communicate with PCM9211.

Feel free to ask any further info, looking for positive replies from you.

Thanks and regards:-

If you can't change clock frequencies dynamically, you might want to look at a sample rate converter such as the SRC4190.
