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
