1.3GHz Prescaler

The MC12075 is a divide by 64 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.

The MC12075 is pin and functionally compatible with the Plessey

SP4633.
