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
