PRELIMINARY
Description
The SD-A2960 Series of quartz crystal oscillators provide DPECL Fast Edge compatible signals. Systems
designers may now specify space-saving, cost-effective packaged PECL oscillators to meet their timing
requirements.
Features
• Wide frequency range–125.0MHz to 312.5MHz
• 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
• Fast rise and fall times <600 ps
• High Reliability - NEL HALT/HASS qualified for
crystal oscillator start-up conditions
• Low Jitter - Wavecrest jitter characterization
available
• Overtone technology
• 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
