Data Sheet 0629H CRYSTAL CLOCK OSCILLATORS Rev. B LVDS HF VCXO SU-A3DCXXX Series Description The SU-A3DCXXX Series of voltage controlled crystal oscillators (VCXO) provides high frequency with LVDS complementary outputs. The outputs can be disabled 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 9x14mm SMD package. Applications and Features • Wide frequency range – 12.0MHz to 280.000MHz • 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 ±100 ppm • SONET ±20 ppm overall free-run stability available • RoHS Compliant, Lead Free Construction Creating a Part Number SU - A 3DC X X X - FREQ Package Code Absolute Pull Range, ppm SU 6 pad 9x14 mm SMD E ±20 F ±32 Input Voltage G ±50 A 3.3V±5% H ±100 9 Customer specific Enable Option H Positive CMOS level 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.
