CRYSTAL CLOCK OSCILLATORS
LVPECL UHF CLOCK (XO)
Data Sheet 0628A Rev. A
SD-A29JXXX Series (3.3 Volt) SD-B29JXXX Series (2.5 Volt)
Description
The SD-X29JXXX Series of quartz crystal oscillators 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 * Tight frequency stability - 20 ppm overall available * Grounded lid and internal by-pass capacitor reduce EMI * RoHS Compliant, Lead Free Construction
