Hi:
Can anyone tell me the clock mismatch value between i2s target FS (44100/48000) and real FS ? Because i'm gonna to move my project from STM32F401 to MK22FN128 .
The picture attached is from STM32F401.
Thanks!!!
Hi
Below picture list K22 I2S/SAI module clock source:
The MCLK could from MCG PLL clock or external input clock.
About MCLK frequency precision is based on clock source, customer could find the MCG PLL clock jitter info from K22 datasheet Table 16. MCG specifications:
If MCLK clock source from external oscillator, it need to check with external oscillator datasheet about clock accuracy data.
Wish it helps.
Have a great day,
Ma Hui
