SLAS538A–OCTOBER 2007–REVISED NOVEMBER 2007
NOTE – when NDAC = 1.5, 2.5, 3.5, 4.5, or 5.5, odd values of Q are not allowed. In this mode, MCLK_x can be
as high as 50 MHz, and f
S(ref)
should fall within 39 kHz to 53 kHz.
When the PLL is enabled,

P), where
P = 1, 2, 3,…, 8
R = 1, 2, …, 16
K = J.D
J = 1, 2, 3, …, 63
D = 0000, 0001, 0002, 0003, …, 9998, 9999
PLLCLK_IN can be MCLK_x or BCLK_x, selected by page 0, register 102, bits D5–D4.
P, R, J, and D are register programmable. J is the integer portion of K (the numbers to the left of the decimal
point), while D is the fractional portion of K (the numbers to the right of the decimal point, assuming four digits of
precision).
Examples:
If K = 8.5, then J = 8, D = 5000
If K = 7.12, then J = 7, D = 1200
If K = 14.03, then J = 14, D = 0300
If K = 6.0004, then J = 6, D = 0004
When the PLL is enabled and D = 0000, the following conditions must be satisfied to meet specified
performance:

Select P = 1, R = 1, K = 7.5264, which results in J = 7, D = 5264
Example:

Select P = 1, R = 1, K = 8.192, which results in J = 8, D = 1920
