LVDS HF/UHF CLOCK (XO)
AA-A2D6XXX Series
Description
The AA-A2D6XXX Series of quartz crystal oscillators provide ultra high frequency with LVDS
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
Wide frequency range 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
Low Phase Noise, Low Jitter
Ultra High Frequency
Fast Rise and Fall times
Tight frequency stability - 20 ppm overall available
RoHS Compliant, Lead Free Construction
Low cost
