Function and Application

Supply voltage pin of

prescalers.

Monitor pin of comparison

frequency at phase detector.

Ground pin of prescalers +

LOout amplifier

Input pin of reference frequency.

This pin should be equipped

with external 16.368 MHz

oscillator (e.g. TCXO).

Supply voltage pin of

input/output amplifiers in

reference block.

Output pin of reference

frequency. The frequency from

pin 19 can be took out as 1 VP-P

swing.

Output pin of 2nd IF amplifier.

This pin output 4.092 MHz

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.

Ground pin of 2nd IF amplifier.
