REGISTER DESCRIPTION
REGISTER 0—INTEGER DIVIDE CONTROL
(DEFAULT: 0x0001C0)
With Register 0, Bits[2:0] set to 000, the on-chip integer divide
control register is programmed as shown in Figure 41.
Divide Mode
Divide mode determines whether fractional mode or integer
mode is used. In integer mode, the RF VCO output frequency
(fVCO) is calculated by
fVCO = 2 × fPFD × (INT)
(1)
where:
fVCO is the output frequency of the internal VCO.
fPFD is the frequency of operation of the phase-frequency detector.
INT is the integer divide ratio value (21 to 123 in integer mode).
Integer Divide Ratio
The integer divide ratio bits are used to set the integer value in
Equation 2. The INT, FRAC, and MOD values make it possible
to generate output frequencies that are spaced by fractions of
the PFD frequency. The VCO frequency (fVCO) equation is
fVCO = 2 × fPFD × (INT + (FRAC/MOD))
(2)
where:
INT is the preset integer divide ratio value (24 to 119 in
fractional mode).
MOD is the preset fractional modulus (1 to 2047).
FRAC is the preset fractional divider ratio value (0 to MOD − 1).
