PECL/LVPECL HF VCXO
SU-X36CXXX Series
Description
The SU-X36CXXX Series of voltage controlled crystal oscillators (VCXO) provides high frequency with
PECL/LVPECL complementary outputs. The outputs can be disabled for test automation or combining
multiple clocks. The device does not use any 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 – 12.0MHz to 280.000MHz
• 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 ±100 ppm
• High shock resistance, to 1000g
• RoHS Compliant, Lead Free Construction
