AB-X29NXXX Series
PECL/LVPECL UHF XO
Description
The AB-X29NXXX Series
of crystal oscillators (XO) 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's packaged in a miniature,
FR-4 based 9x14 mm SMD package
Applications and Features
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
Frequency Range to 1,000 MHz
RoHS compliant, Lead Free Construction
SONET 20 ppm overall stability available
High Shock Resistance, to 1.000 G
