SD-A3670 Series Rev H
Frequency Range: 70.0 MHz to 200.0 MHz
Description
The SD-A3670 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
• Wide Absolute Pull Range
• High Reliability - NEL HALT/HASS qualified for
crystal oscillator start-up conditions
• Low jitter - Wavecrest jitter characterization
available
• Wide frequency range—70.0 MHz to
200.0 MHz
• 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 1000g
• 3.3 Volt operation
• Metal lid electrically connected to ground to
reduce EMI
• 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
