PACKAGE, SEAL & LEAD FINISH Conforms with the Requirements of MIL-PRF-55310 14 7 8 1 All Others GND/CASE -4.5 VDC OUTPUT N/C MISSING NOTE: For PECL applications, Xsis 300 Series ECL oscillators can be operated with +5 VDC + 10% on Pin 14 and power supply return on Pin 7. The output logic levels will still be referenced to +5 VDC and the case will be at +5 VDC, however, 0.8 V peak to peak output signal can be AC or DC coupled as necessary.
