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.
Contact Xsis Engineering for special requirements such as, Output Symmetry, Start-up Time, Frequency Accuracy,
Complementary Outputs, Multiple Outputs, etc.
