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
