LVDS HF VCXO
AB-A3DCXXX Series
Description
The
AB-A3DCXXX Series
of voltage controlled crystal oscillators (VCXO) provides high frequency with
LVDS complementary outputs. The outputs can be disabled for test automation or combining multiple clocks.
The device does not use any frequency multiplication, providing exceptionally low Phase Noise and Jitter
and wide pull. It is packaged in a miniature, FR-4 based 9x14mm SMD package.
Applications and Features
• Wide frequency range – 12.0MHz to 280.000MHz
• 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
• No Multiplication
• Absolute Pull Range (APR) to ±1000 ppm
• SONET ±20 ppm overall free-run stability available
• RoHS Compliant, Lead Free Construction
