10 MHz
≤ PLLCLK _IN / P ≤ 20 MHz
80 MHz
≤ PLLCLK _IN × K × R / P ≤ 110 MHz

≤ J ≤ 11
R = 1
Example:
For MCLK = 12 MHz, fS = 44.1 kHz, NADC = 8, MADC = 2, and AOSR = 128:
Select P = 1, R = 1, K = 7.5264, which results in J = 7, D = 5264
Example:
For MCLK = 12 MHz, fS = 48 kHz , NADC = 8, MADC = 2, and AOSR = 128:
Select P = 1, R = 1, K = 8.192, which results in J = 8, D = 1920
The following table lists several example cases of typical MCLK rates and how to program the PLL to achieve
sample rates of fS = 44.1 kHz or 48 kHz with NADC = 8, MADC = 2, and AOSR = 128.
