CIRCUIT DESCRIPTION
REFERENCE INPUT SECTION
The reference input stage is shown in Figure 11. SW1 and SW2
are normally closed switches. SW3 is normally open. 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 12. It is followed by a
2-stage limiting amplifier to generate the current-mode logic
(CML) clock levels needed for the prescaler.

RF INT DIVIDER
The RF INT CMOS counter allows a division ratio in the PLL
feedback counter. Division ratios from 31 to 511 are allowed.
INT, FRAC, MOD, AND R RELATIONSHIP
The INT, FRAC, and MOD values, in conjunction with the
R counter, make it possible to generate output frequencies that
are spaced by fractions of the phase frequency detector (PFD).
See the RF Synthesizer: A Worked Example section for more
information. The RF VCO frequency (RFOUT) equation is
RFOUT = FPFD × (INT + (FRAC/MOD))
(1)
where:
RFOUT is the output frequency of the external voltage controlled
oscillator (VCO).
INT is the preset divide ratio of the binary 9-bit counter (31
to 511).
MOD is the preset fractional modulus (2 to 4095).
FRAC is the numerator of the fractional division (0 to MOD 1).
The PFD frequency is given by:
FPFD = REFIN × (1 + D)/R
(2)
where:
REFIN is the reference input frequency.
D is the REFIN doubler bit.
R is the preset divide ratio of the binary 4-bit programmable
reference counter (1 to 15).
RF R COUNTER
The 4-bit RF R counter allows the input reference frequency
(REFIN) to be divided down to produce the reference clock to
the PFD. Division ratios from 1 to 15 are allowed.
