CIRCUIT DESCRIPTION  
Reference Input Section  
Prescaler  
The dual modulus prescaler (P/P + 1), along with the A and  
B counters, enables the large division ratio, N, to be realized  
(N = BP + A). This prescaler, operating at CML levels, takes  
the clock from the IF/RF input stage and divides it down to a  
manageable frequency for the CMOS A and B counters. It is  
based on a synchronous 4/5 core.  
The reference input stage is shown in Figure 2. 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.  
The prescaler is selectable. On the IF side, it can be set to either 8/9  
(DB20 of the IF AB Counter Latch set to 0) or 16/17 (DB20 set  
to 1). On the RF side of the ADF4217L/ADF4218L, it can be set  
to 64/65 or 32/33. On the ADF4219L, the RF prescaler can be  
set to 16/17 or 32/33. See Tables V, VI, VIII, and IX.

SW1  
The A and B CMOS counters combine with the dual modulus  
prescaler to allow a wide ranging division ratio in the PLL feed-  
back counter. The devices are guaranteed to work when the  
prescaler output is 188 MHz or less. Typically they will work  
with 250 MHz output from the prescaler.

IF/RF Input Stage  
The IF/RF input stage is shown in Figure 3. It is followed by a  
two-stage limiting amplifier to generate the CML clock levels  
needed for the prescaler.
