CRYSTAL OSCILLATORS Data Sheet 0629K AB-X32AXXX-X Series CMOS/LVCMOS HF VCXO Rev. R Description The AB-X32AXXX Series of voltage controlled crystal oscillators (VCXO) provides high frequency with CMOS/LVCMOS outputs. The outputs can be Tri-stated for test automation or combining multiple clocks. The device does not use any frequency multiplication, providing exceptionally low Phase Noise and Jitter and wide pull. It’s packaged in a miniature, FR-4 based 9x14 mm SMD package Applications and Features • Wide frequency range – 12.0MHz to 250.000MHz • • • • • • • • Fiber Channel; 10 GbE; Infiniband; Network Processors; SONET/SDH High Reliability – NEL HALT/HASS qualified for crystal oscillator start-up conditions Extremely Low Phase Noise and Jitter High Shock Resistance, to 1000g No Multiplication Absolute Pull Range (APR) to ±1000 ppm SONET ± 20 ppm overall free-run stability available COTS/Dual use Creating a Part Number AB - X 32A X X X – X - FREQ Package code AB 6 pad 9x14 mm SMD Environmental L Contains a level of lead that is in excess of RoHs directive and is not designed for reflow R RoHS compliant Operating Voltage 0 5.0V ± 5% A 3.3V ± 5% B 2.5V ± 5% Tri-State Option T Tri-state N N/A Temperature Range, ºC A 0 to 50 B 0 to 70 C -20 to 70 D -40 to 85 9 Customer Specific Absolute Pull Range, ppm E ±20 F ±32 G ±50 H ±100 9 Customer specific 357 Beloit Street, P.O.
