Data Sheet 0629K CRYSTAL CLOCK OSCILLATORS Rev. D CMOS/LVCMOS HF VCXO SU-X32AXXX Series Description The SU-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. It is 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, Low Jitter • No Multiplication • SONET ±20ppm overall free-run stability available • Absolute Pull Range (APR) to ±100 ppm • High shock resistance, to 1000g • RoHS Compliant, Lead Free Construction Creating a Part Number SU - X 32A X X X - FREQ Package Code Absolute Pull Range, ppm SU 6 pad 9x14mm SMD E ±20 F ±32 Input Voltage G ±50 5.0V±5% H ±100 A 3.3V±5% 9 Customer specific B 2.5V±5% Tri-State Option T Tri-state N N/A 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.
