Description
The SD-X2980 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
• Wide frequency range - 25.0MHz to 312.5MHz
• User specified tolerance available
• Space-saving alternative to discrete component
oscillators
• High shock resistance, to 1000g
• High Reliability - NEL HALT/HASS qualified for
crystal oscillator start-up conditions
• COTS/Dual use
