OCXO
Oven Controlled Crystal Oscillator. A crystal oscillator maintained, during operation, at a fixed temperature so that frequency changes due to ambient temperature changes do not affect its performance.
 

On Time Marker (OTM)
The part of a time code that is synchronized to the UTC second.
 

Operable temperature
The temperature range over which the oscillator may be operated without damage. The oscillator is not required to perform within specification over this range. To avoid confusion this parameter is normally not specified and will never be specified when its values are the same as operating temperature.
 

Operating current
See supply current
 

Operating temperature
The temperature range over which the oscillator will operate within its specifications.
 

Operating voltage
See supply voltage.
 

Output impedance
A specification that allows calculation of the change in output amplitude with changing load impedance.
 

Output power
The output power calculated from the rms output voltage and the load impedance or measured directly. It is usually specified in dBm into a 50 ohm load. See Dealing with dBm for further information.
 

Output voltage
The specified output voltage magnitude and waveform. It may be specified in several different ways: TTL output, HCMOS output, 1 volt +/- 25% Sine wave output, or as output power.
 

Overall frequency accuracy
The maximum permissible frequency deviation of the oscillator due to all combinations of specified operating and environmental parameters within a specified period of time. This applies to fixed frequency oscillators.
 

Overall frequency stability
The maximum permissible frequency deviation of the oscillator due to all combinations of specified operating and environmental parameters within a specified period of time and at a fixed tuned frequency. This applies to oscillators which may be tuned.
 

Overshoot
A characteristic of circuits employing high performance rectangular wave techniques. Overshoot is the tendency of the rising and falling edges of the signal to have a damped oscillation superimposed upon them causing the voltage to momentarily rise above the normal peak signal voltage by as much as several volts.
