SU-A3699-FREQ

CRYSTAL CLOCK OSCILLATORS VCXO Series (PECL) Data Sheet 0515F Rev. F SU-A369X Series PATENT PENDING Description The SU-A369X Series of voltage controlled quartz crystal oscillators provide frequency control by applying a voltage to Pin 1. This unit supplies DPECL compatible outputs which are enabled when Pin 2 is set to a logic low or left open. Features • Frequency range–300.0MHz to 1.500GHz • Wide Absolute Pull Range • Will withstand SMD reflow temperatures of 183°C for 4 minutes maximum • Space-saving alternative to discrete component oscillators • High shock resistance, to 1000g • 3.3 volt operation • Low Jitter - Wavecrest jitter characterization available • High Reliability - NEL HALT/HASS qualified for crystal oscillator start-up conditions • High Q Crystal actively tuned oscillator circuit • Power supply decoupling internal • No internal PLL avoids cascading PLL problems • High frequencies due to proprietary design • Gold plated pads Electrical Connection Pad 1 2 3 4 5 6 Connection VCO Enable VEE Output Output Complement VCC 357 Beloit Street, P.O.
