CRYSTAL CLOCK OSCILLATORS
LVDS HF/UHF CLOCK (XO)
Data Sheet 0631E Rev. -
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
