Hi ,

I am giving to MCLK from external crystal as 12288000. With this clock, can i generate 44.1khz and 48khz using PLL.If possible please help to get the divider values(P,J,D,R,NDAC,MDAC,DOSR).

    Hi Mani,

    If you have MCLK = 12.288MHz you can set the following values for the clock setting registers:
    48kHz -> PLL = OFF, NDAC = 1, MDAC = 2, DOSR = 128
    44.1kHz -> PLL = ON, PLL_P = 1, PLL_R = 1, PLL_J = 6, PLL_D = 8906, NDAC = 3, MDAC = 5, DOSR = 128

    Best regards,
