VCXO Series (PECL)

PJ-A3670 Series

PRELIMINARY

Description

The PJ-A3670 Series of voltage controlled quartz crystal oscillators provide frequency control by applying a
voltage to Pin 1. This unit supplies ECLiPS compatible outputs which are enabled when Pin 2 is set to a
logic high or left open.

Features

• Frequency range–80.0MHz to 162.0MHz

• User specified tolerance available

• Will withstand vapor phase temperatures of 253°C
for 4 minutes maximum

• Space-saving alternative to discrete component
oscillators

• High shock resistance, to 3000g

• 3.3 volt operation

• Metal lid electrically connected to ground to
reduce EMI

• Low Jitter - Wavecrest jitter characterization
available

• High Reliability - NEL HALT/HASS qualified for
crystal oscillator start-up conditions

• High Q Crystal actively tuned oscillator circuit

• Power supply decoupling internal

• No internal PLL avoids cascading PLL problems

• High frequencies due to proprietary design

• Gold plated leads - Solder dipped leads available
upon request
