SEMICONDUCTOR TECHNICAL DATA
1.1GHz Prescaler
The MC12074 is a divide by 256 prescaler. Typical frequency
synthesis applications include elctronically tuned TV/CATV and
communication systems as well as instrumentation.
An internal preamplifier is included which isolates the differential inputs
and provides gain for the input signal. Differential PECL outputs are
provided.
