PECL/LVPECL UHF VCXO
AB-X36DXX Series
Description
The
AB-X36DXXX Series
of voltage controlled crystal oscillators (VCXO) provides ultra high frequency with
PECL/LVPECL 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 9x14 mm 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, Low Jitter
• SONET ±20ppm overall free-run stability available
• Absolute Pull Range (APR) to ±1000 ppm
• High shock resistance, to 1000g
• RoHS Compliant, Lead Free Construction
