| CRYSTAL CLOCK OSCILLATORS Data Sheet 0629J Rev. B PECL/LVPECL HF VCXO SU-X36CXXX Series Description The SU-X36CXXX Series of voltage controlled crystal oscillators (VCXO) provides high frequency with PECL/LVPECL 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 9x14 mm 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, 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 36C X X X - FREQ Package Code Absolute Pull Range, ppm SU 6 pad 9x14mm SMD E 20 F 32 Input Voltage G 50 5.0V5% H 100 A 3.3V5% 9 Customer specific B 2.5V5% 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.
