LVPECL HF/UHF CLOCK (XO)
AA-X29LXXX-X Series
Description
The
AA-X29LXXX Series
of quartz crystal oscillators provides ultra high frequency with LVPECL
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
• Ultra High Frequency – 10.0MHz to 625.000MHz
• Fiber Channel; 10 GbE; Infiniband; Network Processors; SOHO Routing
• High Reliability - NEL HALT/HASS qualified for crystal oscillator start-up conditions
• Fast Rise and Fall times
• Tight frequency stability - ±20 ppm overall available
• Low cost
• COTS/Dual use
