LVPECL UHF VCXO
SD-X36AXXX Series
Description
The SD-X36AXXX Series of voltage controlled crystal oscillators (VCXO) provides ultra high frequency with LVPECL complementary outputs. The outputs can be Tri-stated for test automation or combining multiple clocks. The device is based on advanced PLL 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
