CMOS/LVCMOS HF VCXO
AB-X32AXXX Series
Description
The
AB-X32AXXX Series
of voltage controlled crystal oscillators (VCXO) provides high frequency with
CMOS/LVCMOS outputs. The outputs can be Tri-stated 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 9x14 mm SMD package.
Applications and Features
• Wide frequency range – 12.0MHz to 250.000MHz
• 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, Low Jitter
• No Multiplication
• SONET ±20ppm overall free-run stability available
• Absolute Pull Range (APR) to ±1000 ppm
• High shock resistance, to 1000g
• RoHS Compliant, Lead Free Construction
