LVPECL HF/UHF CLOCK (XO)

AA-X29LXXX Series

Description

The AA-X29LXXX Series of quartz crystal oscillators provides ultra high frequency with LVPECL

complementary outputs. The outputs can be disabled for test automation or combining multiple clocks. The

device is based on low noise analog harmonic multiplication, and packaged in a miniature, low profile

leadless FR4 based package with gold plated pads, which enhances compatibility with PCB material.

Applications and Features

• Ultra High Frequency – 150.0MHz to 500.000MHz

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

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

• Fast Rise and Fall times

• Tight frequency stability - ±20 ppm overall available

• RoHS Compliant, Lead Free Construction

• Low cost
