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 253°C
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
