LVDS UHF VCXO
SD-A3DBXXX Series
Description
The SD-A3DBXXX Series of voltage controlled crystal oscillators (VCXO) provides ultra high frequency with
LVDS complementary outputs. The outputs can be Tri-stated for test automation or combining multiple
clocks. The device is based on low noise analog harmonic multiplication for higher frequencies, and
packaged in a miniature, low profile leadless ceramic SMD package with 6 gold plated pads.
Applications and Features
• Wide frequency range – 38.0MHz to 640.000MHz
• Fiber Channel; 10 GbE; Infiniband; Network Processors; SOHO Routing
• High Reliability - NEL HALT/HASS qualified for crystal oscillator start-up conditions
• Low Phase Noise, Low Jitter
• High shock resistance, to 1000g
• Ultra High Frequency
• Absolute Pull Range (APR) to ±100 ppm
• Grounded lid and internal by-pass capacitor reduce EMI
• RoHS Compliant, Lead Free Construction
