PRODUCTION DATA.
The N divider of each PLL includes fractional compensation and can achieve any fractional denominator (DEN) from 1 to 4,194,303. The integer portion, INT, is the whole part of the N divider value and the fractional portion, NUM / DEN, is the remaining fraction. N, NUM, and DEN are programmed in R58, R59, R60, R61, R62, R63, R64, and R65 for PLL1 and in R73, R74, R75, R76, R77, R78, R79, and R80 for PLL2. The total programmed N divider value, N, is determined by: N = INT + NUM / DEN. The output of the N divider sets the PFD frequency to the PLL and should be in the range of 1 MHz to 150 MHz.
