CRYSTAL OSCILLATORS

Data Sheet 0645A

AB-X29NXXX Series PECL/LVPECL UHF XO

Description

The AB-X29NXXX Series of crystal oscillators (XO) provides ultra high frequency with PECL/LVPECL complementary outputs. The outputs can be disabled for test automation or combining multiple clocks. The device is based on low noise analog harmonic frequency

multiplication, providing exceptionally low Phase Noise and Jitter. It’s packaged in a miniature, FR-4 based 9x14 mm SMD package

Applications and Features

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 Frequency Range to 1,000 MHz

RoHS compliant, Lead Free Construction SONET ± 20 ppm overall stability available High Shock Resistance, to 1.000 G
