MC12074

MOTOROLA SEMICONDUCTOR TECHNICAL DATA 1.1GHz Prescaler MC12074 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.
