Description
The SD-A2980 Series of quartz crystal oscillators provide DPECL compatible signals. Systems designers may
now specify space-saving, cost-effective packaged PECL oscillators to meet their timing requirements.
Features
• High Reliability - NEL HALT/HASS qualified for
crystal oscillator start-up conditions
• Low jitter - Wavecrest jitter characterization avail-
able
• Wide frequency range—80.0 MHz to 540.0 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
• Overtone technology
• High Q crystal actively tuned oscillator circuit
• No internal PLL avoids cascading PLL problems
• High frequencies due to proprietary design
• Gold plated pads
