** Deviation is referenced to the specified output frequency . For example,
inModel CO-484V-EX @ 100 MHz, at 25°C and 0V control, the frequency is at
least 100 ppm below 100 MHz and at +5V the frequency is at least 100 ppm above
100 MHz.
*The following notes apply to options C,F,I,L and N (±200 ppm deviation);
- They are available at frequencies up to 75 MHz in all models
- Linearity of ±10% is standard to 75 MHz.

positive transfer function (lowest frequency at 0 V)
*±3 V to ± 10 V optional
*With bipolar control voltage option, transfer function is
negative, and linearity is ±10%

|
Linearity
|
±20% (±10% optional); ±10% is standard with bipolar control voltage
and with deviation/stability options C, F, I, L and N.
