| CRYSTAL CLOCK OSCILLATORS Data Sheet 0541A Rev. - VCXO Series (CMOS) SH-A3200 Series PRELIMINARY Description The SH-A3200 Series of voltage controlled quartz crystal oscillators provide frequency control by applying a voltage to Pin 1. This unit supplies a CMOS compatible output which are enabled when Pin 2 is set to a logic high or left open. Features * Wide frequency range 60.0MHz to 160.0MHz * Will withstand vapor phase temperatures of 253C for 4 minutes maximum * Space-saving alternative to discrete component oscillators * High shock resistance, to 1000g * 3.3 or 2.5 volt operation * Metal lid electrically connected to ground to reduce EMI * 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 * RoHS Compliant, Lead Free Construction Electrical Connection Pad 1 2 3 4 5 6 Connection VCO Enable Ground Output NC VDD 357 Beloit Street, P.O.
