3GHz Prescaler
The MC12078 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.
