MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
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.
