PECL/LVPECL UHF VCXO
AB-X36DXXX 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
