question about the SAI clock and example in cubeL4

for the SAI example in cubeL4, it looks like running 22050 sample rate, and the input clock is 11.294M.
I measure the frame len is about 45us which is 1/22050.
Now I develop an audio app runs 44100,  I have checked the data sheet, seems only way is to double the PLLSAI1, but most closest setting I get is 22.85M which is not fit very well.
I think the measured frame len for 44100 sample rate should be about 1/44100=27us. I use this meathod to verify the clock setting.
May I know any guys work on SAI 44100? have the right clock setting(not use external one)? or any setting can based on 11.294MHZ PLLSAI to make 44100 working?

 thanks a lot
