Data Sheet 0648B CRYSTAL OSCILLATORS Rev. J CMOS/LVCMOS HF VCTCXO AB-XC3XXX-X Series Description The AB-XC3XXX Series of voltage controlled, temperature compensated crystal oscillators (VCTCXO) provides high frequency with CMOS/LVCMOS output. The outputs can be tristated for test automation or combining multiple clocks. The device does not use any frequency multiplication, providing exceptionally low Phase Noise and Jitter. It’s packaged in a miniature, FR-4 based 9x14 mm SMD package Applications and Features • • • • • • • 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 No Multiplication Frequency Stability from ± 5 ppm High Shock Resistance, to 1000g COTS/Dual use Creating a Part Number AB - X C3 X X X – X - FREQ Package code AB 6 pad 9x14x 6.1mm SMD Operating Voltage 0 5.0 V ± 5% A 3.3 V ± 5% B 2.5 V ± 5% C 1.8 V ± 5% Tristate Option T - tristate N – N/A Environmental L Contains a level of lead that is in excess of RoHS directive and is not designed for reflow R RoHS compliant Temp.
