LVDS UHF VCXO
AB-A3DBXXX Series
Description
The AB-A3DBXXX Series of voltage controlled crystal oscillators (VCXO) provides 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 frequency multiplication, providing exceptionally low
Phase Noise and Jitter. It is packaged in a miniature, FR-4 based 9x14mm SMD package.
Applications and Features
• Wide frequency range – 200.0MHz to 1.000GHz
• Fiber Channel; 10 GbE; Infiniband; Network Processors; SONET/SDH
• High Reliability - NEL HALT/HASS qualified for crystal oscillator start-up conditions
• Extremely Low Phase Noise and Jitter
• High shock resistance, to 1000g
• Absolute Pull Range (APR) to ±1000 ppm
• SONET ±20 ppm overall free-run stability available
• RoHS Compliant, Lead Free Construction
