HCSL COMPATIBLE HF/UHF CLOCK (XO)
AA-XEXX Series
Description
The AA-XEXX Series of quartz crystal oscillators provide ultra high frequency with HCSL compatible
complementary outputs. The device is based on low noise analog harmonic multiplication, and packaged in
a miniature, low profile leadless FR-4 based package with gold plated pads, which enhances compatibility
with PCB material.
Applications and Features
Ultra High Frequency up to 240.000MHz
Fiber Channel; 10 GbE; Infiniband; Network Processors; SONET/SDH
High Reliability - NEL HALT/HASS qualified for crystal oscillator start-up conditions
Low Phase Noise, Low Jitter
Fast Rise and Fall times
Tight frequency stability - 20ppm overall available
RoHS Compliant, Lead Free Construction
Low cost
