CRYSTAL CLOCK OSCILLATORS
Data Sheet 0306A Rev. P
Differential Positive ECL (DPECL)
SD-B2980 Series
Description
The SD-B2980 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–60.0MHz to 312.5MHz User specified tolerance available Space-saving alternative to discrete component oscillators High shock resistance, to 1000g 2.5 volt operation Overtone technology High Reliability - NEL HALT/HASS qualified for crystal oscillator start-up conditions Wavecrest jitter characterization available High Q Crystal actively tuned oscillator circuit No internal PLL avoids cascading PLL problems Power supply decoupling internal Metal lid electrically connected to ground to reduce EMI Gold plated pads RoHS Compliant, Lead Free Construction
