Dear experts,
We want to set WCLK at 44.1KHz with MCLK=24MHz.
However, after we set the parameters, the WCLK output was not correct ( it shows in 38kHz).
The parameters are set as follows: NDAC=8, MDAC=1, DOSR=128, J=4, R=4, P=5, D=704, PLL_CLKIN_DIV=2 (PLL CLK selects MCLK)
Based on formula DAC_FS=DAC_CLKIN/(NDAC*MDAC*DOSR)
DAC_CLKIN=PLL_CLK_out=(PLL_CLKIN*R*J.R)/(P*PLL_CLK_in_DIV)=(24000000*4*4.704)/(5*2)=45158400
DAC_FS=45158400/(8*1*128)=44100
The waveform is as below:
WCLK: (38KHz)
MCLK: (24MHz)
Is there anything we miss or something wrong in our calculation so that we could not get 44.1KHz WCLK output?
Thank you.
Best Regards,
Cindy
