Description
The PJ-A2920 Series of quartz
crystal oscillators provide ECLIPS
compatible signals. Systems
designers may now specify space-
saving, cost-effective packaged
PECL oscillators to meet their
timing requirements.
Features
[] Wide frequency range -
50.0MHz to 200.000MHz
[] User specified tolerance from
20ppm
[] Will withstand vapor phase
temperatures of 253C for 4
minutes maximum.
[] ECLIPS compatible output on Pin
4, complement on Pin 1
[] High shock resistance, to 3000G
[] 3.3 Volt operation
[] Fast rise and fall times, <600 ps
[] Metal lid electrically connected
to ground to reduce EMI
[] Gold plated leads -
Solder dipped leads available
Upon request.
