| CRYSTAL CLOCK OSCILLATORS Differential Positive ECL (DPECL) Fast Edge Data Sheet 0350C Rev. G PJ-B2980 Series Description The PJ-B2980 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-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 * Metal lid electrically connected to ground to reduce EMI * 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 * RoHS Compliant, Lead Free Construction Electrical Connection Pin 1 2 3 4 5 6 Connection Enable/Disable N.C.

Please contact factory for full Wavecrest characterization. RMS jitter bandwidth of 12kHz to 20MHz. 4) Tpd is phse shift between the falling edge of pin 4 at 2.0V and the rising edge of pin 5 at 2.01V. 5) Open to enable pin also enables the output. 6) Internal high frequency power source decoupling.
