CRYSTAL OSCILLATORS

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
