SD-B2980 Datasheet | NEL

Description The SD-B2980 Series of quartz crystal oscillators provide DPECL patible 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 ponent 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 - Ro HS pliant, Lead Free Construction Electrical Connection Pin 1 2 3 4 5 6 Connection Enable/Disable N.C.
