Configuring clocks on ADSP-21565

Category: Hardware
Product Number: ADSP-21565

Hello,

I work on a custom board with an ADSP-21565.

I am searching for information regarding clock configuration (SYSCLK, CCLK, and SCLK). How to chose frequencies (tradeoffs?) and how to configure them.

For example I read on this forum that by default SCLK is 93.75MHz, and it seems to be the case with my experimentations. Is there an official information about this?

I work on an audio product with DACs, ADCs and need to implement I2S and TDM communications. Audio will be running at 48kH. I have a separate clock coming into the DSP from a DAI for driving audio communications (DACs receive the same), so I am not sure the DSP clocks are so relevant to me. Could you provide guidance regarding those subjects?

My project will integrate SigmaStudio.

Thanks a lot,

Fabien
