Technical Data
254
The output of CGM clock is a standard CMOS output with push-pull
configuration. The output logic high and low levels are specified with
corresponding DC loading current (see
Characteristics). The transient current is mainly determined by the
maximum loading capacitor value.
The relationship between the VCO frequency, f
