Function and Application
Supply voltage pin of
prescalers.
Monitor pin of comparison
frequency at phase detector.
Ground pin of prescalers +
LOout amplifier
Non connection
Input pin of reference frequency.
This pin should be equipped
with external 16.368 MHz
oscillator (example: TCXO).
Non connection
Supply voltage pin of
input/output amplifiers in
reference block.
Output pin of reference
frequency. The frequency from

clipped sinewave.
This pin should be equipped
with external inverter to adjust
level to next stage on user’s
system.
Supply voltage pin of 2nd IF
amplifier.
Bypass pin of 2nd IF amplifier
input 1. This pin should be
grounded through capacitor.
Pin of 2nd IF amplifier input 2.
This pin should be grounded
through capacitor.
Pin of 2nd IF amplifier input 1.
2nd IF filter can be inserted
between pin 26 & 28.
