Figure 33. Integer Divide Control Register (R0)
Register 0—Integer Divide Control
With R0[2:0] set to 000, the on-chip integer divide control register
is programmed as shown in Figure 33. The internal VCO
frequency (fVCO) equation is
fVCO = fPFD × (INT + (FRAC/MOD)) × 2
(1)
where:
fVCO is the output frequency of the internal VCO.
INT is the preset integer divide ratio value (21 to 123 for integer
mode, 24 to 119 for fractional mode).
MOD is the preset fractional modulus (1 to 2047).
FRAC is the preset fractional divider ratio value (0 to MOD 1).
The integer divide ratio sets the INT value in Equation 1. The
INT, FRAC, and MOD values make it possible to generate output
frequencies that are spaced by fractions of the PFD frequency.
Note that the demodulator LO frequency is given by fLO = fVCO/4.
Divide Mode
Divide mode determines whether fractional mode or integer mode
is used. In integer mode, the VCO output frequency, fVCO, is
calculated by
fVCO = fPFD × (INT) × 2
