AB-X3A2XX-X Series

SINEWAVE VCXO

Description

The AB-X3A2XX Series

of voltage controlled crystal oscillators (VCXO) provides high

frequency with Sinewave outputs. The device does not use any frequency multiplication, providing

exceptionally low Phase Noise and Jitter and wide pull. It’s packaged in a miniature, FR-4 based

9x14 mm SMD package

Applications and Features

•

Wide frequency range – 12.0MHz to 250.000MHz

•

Fiber Channel; 10 GbE; Infiniband; Network Processors; SONET/SDH

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

Extremely Low Phase Noise and Jitter

High Shock Resistance, to 1000g

No Multiplication

Absolute Pull Range (APR) to ±1000 ppm

SONET ± 20 ppm overall free-run stability available
