LVPECL UHF CLOCK (XO)
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
