Differential Positive ECL (DPECL)

Fast Edge

SD-A2920 Series

Description

The SD-A2920 Series of quartz crystal oscillators provide DPECL Fast Edge compatible signals. Systems

designers may now specify space-saving, cost-effective packaged PECL oscillators to meet their timing

requirements.

Features

• Wide frequency range–75.0MHz to 250.0MHz

(Preliminary from180+MHz to 250MHz)

• 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 1000g

• 3.3 volt operation

• Metal lid electrically connected to ground to

reduce EMI

• Fast rise and fall times <600 ps

• Low Jitter - Wavecrest jitter characterization

available

• High Reliability - NEL HALT/HASS qualified for

crystal oscillator start-up conditions

• Overtone technology

• 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 pads
