CRYSTAL CLOCK OSCILLATORS
HCSL COMPATIBLE HF/UHF CLOCK (XO)
Data Sheet 0631D Rev. A
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
