NEL SD-A2D7H99-FREQ

Data Sheet 0642A
CRYSTAL CLOCK OSCILLATORS
Rev. LVDS UHF CLOCK (XO)
SD-A2D7XXX Series
Description
The SD-A2D7XXX Series of quartz crystal oscillators 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 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 – 0.75MHz to 800.000MHz
• 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
