CIRCUIT DESCRIPTION
REFERENCE INPUT SECTION
The reference input stage is shown in Figure 14. SW1 and SW2
are normally closed switches (NC in Figure 14). SW3 is normally
open (NO in Figure 14). When power-down is initiated, SW3 is
closed and SW1 and SW2 are opened. This ensures that there is
no loading of the REFIN pin on power-down.

RF INPUT STAGE
The RF input stage is shown in Figure 15. It is followed by a
two-stage limiting amplifier to generate the current-mode logic
(CML) clock levels needed for the prescaler.

PRESCALER (P/P + 1)
Together with the A and B counters, the dual-modulus prescaler
(P/P + 1) enables the large division ratio, N, to be realized by
N = BP + A
The dual-modulus prescaler, operating at CML levels, takes the
clock from the RF input stage and divides it down to a manageable
frequency for the CMOS A and CMOS B counters. The pre-
scaler is programmable; it can be set in software to 8/9, 16/17,
32/33, or 64/65. It is based on a synchronous 4/5 core.
A AND B COUNTERS
The A and B CMOS counters combine with the dual-modulus
prescaler to allow a wide ranging division ratio in the PLL
feedback counter. The counters are specified to work when the
prescaler output is 200 MHz or less (for AVDD = 5 V). Thus,
with an RF input frequency of 2.5 GHz, a prescaler value of
16/17 is valid but a value of 8/9 is not.
Pulse Swallow Function
The A and B counters, in conjunction with the dual-modulus
prescaler, make it possible to generate output frequencies that
are spaced only by the reference frequency divided by R. The
equation for the VCO frequency is
fVCO = [(P × B) + A]fREFIN/R
where:
fVCO = output frequency of external voltage controlled
oscillator (VCO).
P = preset modulus of dual-modulus prescaler.
B = preset divide ratio of binary 13-bit counter (3 to 8191).
A = preset divide ratio of binary 6-bit swallow counter (0 to 63).
fREFIN = output frequency of the external reference frequency
oscillator.
R = preset divide ratio of binary 14-bit programmable reference
counter (1 to 16,383).

R COUNTER
The 14-bit R counter allows the input reference frequency to be
divided down to produce the reference clock to the phase fre-
quency detector (PFD). Division ratios from 1 to 16,383 are
allowed.
