CIRCUIT DESCRIPTION
REFERENCE INPUT SECTION
The reference input stage is shown in Figure 16. 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 REF
IN
pin
on power-down.

RF INPUT STAGE
The RF input stage is shown in Figure 17. 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 (

programmable FRAC counter (2 to 4095).
FRAC

programmable FRAC counter (0 to MOD).
RF R COUNTER
The 4-bit RF R counter allows the input reference frequency
(REF
IN
) to be divided down to produce the reference clock to
the PFD. Division ratios from 1 to 15 are allowed.
