LVPECL UHF VCXO

SD-X36BXXX Series

Description

The SD-X36BXXX Series of voltage controlled crystal oscillators (VCXO) provides ultra high frequency with

LVPECL complementary outputs. The outputs can be Tri-stated for test automation or combining multiple

clocks. The device is based on low noise analog harmonic multiplication for higher frequencies, and

packaged in a miniature, low profile leadless ceramic SMD package with 6 gold plated pads.

Applications and Features

• Wide frequency range – 38.0MHz to 800.000MHz

• Fiber Channel; 10 GbE; Infiniband; Network Processors; SOHO Routing

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

• Low Phase Noise, Low Jitter

• High shock resistance, to 1000g

• Ultra High Frequency

• Absolute Pull Range (APR) to ±100 ppm

• Grounded lid and internal by-pass capacitor reduce EMI

• RoHS Compliant, Lead Free Construction
