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

ow or left open.

Features

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

• Low jitter - Wavecrest jitter characterization avail­able

• Frequency range—70.0 MHz to

200.0 MHz

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

• Space-saving alternative to discrete component
oscillators

• Wide Absolute Pull Range

• High shock resistance, to 3000g

• 3.3 Volt operation

• Metal lid electrically connected to ground to
reduce EMI

• High Q crystal actively tuned oscillator circuit

• Power supply decoupling internal

• No internal PLL

°C

• High frequencies due to proprietary design

• Gold plated leads—Solder dipped leads available
upon request

• RoHS Compliant, Lead Free Construction
(unless solder dipped leads are supplied)

avoids cascading PLL problems
