I2S frequency

Hello,

I am using S32K142 EVB to configure I2S on flexIO.

although I Go through datasheet and I2S example code, I'm still confused about clock frequencies.

Please suggest standard/suggested frequencies for MCLK, SCLK and LRCK for transmitting sound.

also, How can I configure LRCK (word select) frequency in S32 Design Studio?

 

if you have any sample code for only I2S other than SDK provided example please share with me.

 

Thanks!!

Hi @MohitManvar 

there are no more resources for S32K1 but there are some application notes for other devices. Maybe this one could help:
