CRYSTAL CLOCK OSCILLATORS Data Sheet 0209B Rev. D VCXO Series (PECL) PJ-A3670 Series PRELIMINARY Description The PJ-A3670 Series of voltage controlled quartz crystal oscillators provide frequency control by applying a voltage to Pin 1. This unit supplies ECLiPS compatible outputs which are enabled when Pin 2 is set to a logic high or left open. Features * Frequency range-80.0MHz to 162.0MHz * User specified tolerance available * Will withstand vapor phase temperatures of 253C for 4 minutes maximum * Space-saving alternative to discrete component oscillators * High shock resistance, to 3000g * 3.3 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 leads - Solder dipped leads available upon request Electrical Connection Pin Connection 1 2 3 4 5 VCO Output Enable VEE Output Output Complement VCC 6 357 Beloit Street, P.O.
