SD-B29KHCE-FREQ

CRYSTAL CLOCK OSCILLATORS Data Sheet 0628B Rev. B LVPECL UHF CLOCK (XO) SD-A29KXXX Series (3.3 Volt) SD-B29KXXX Series (2.5 Volt) Description The SD-X29KXXX 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 low noise analog harmonic 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 Creating a Part Number SD - X 29K X X X - FREQ Package Code Overall Frequency Stability, ppm SD 6 pad 5x7mm SMD E ±20 F ±25 Input Voltage G ±50 A 3.3V±5% H ±100 B 2.5V±5% 9 Customer specific Enable Option H Enable High L Enable Low Temperature Range, °C A 0 to 50 B 0 to 70 C -20 to 70 D -40 to 85 9 Customer specific 357 Beloit Street, P.O.
