Test Pin
The Test pin, Pin 19, is a buffered logic input which is exclusively
ORed with the output of the prescaler. The output of the XOR gate
is the input to the MAIN divider. The Test pin must be connected to
V
DD
during normal operation as a synthesizer. This pin can be used
as an input for verifying the divide ratio of the MAIN divider; while in
this condition the input to the prescaler, RF
IN
, may be connected to
V
CCP
through a 10k
resistor in order to place prescaler output into
a known state.
