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
