SINE-WAVE UHF VCXO
AB-A3A1XX Series
Description
The
AB-A3A1XX Series
of voltage controlled crystal oscillators (VCXO) provides ultra high frequency with a
single-ended sine-wave output. 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
