| CRYSTAL CLOCK OSCILLATORS LVDS UHF VCXO Data Sheet 0629D Rev. - SD-A3DAXXX Series Description The SD-A3DAXXX Series of voltage controlled crystal oscillators (VCXO) 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 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 * Absolute Pull Range (APR) to 100 ppm * Grounded lid and internal by-pass capacitor reduce EMI * RoHS Compliant, Lead Free Construction Creating a Part Number SD - A 3DA X X X - FREQ Package Code Absolute Pull Range, ppm SD 6 pad 5x7mm SMD E 20 F 32 Input Voltage G 50 A 3.3V5% H 100 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.
