SEMICONDUCTOR TECHNICAL DATA
1.3GHz Prescaler
The MC12076 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.
• 1.3GHz Toggle Frequency
• Operating Supply Voltage of 4.5 to 5.5V
• Low–Power 36mA Typical at VCC = 5.0V
• Operating Temperature Range of 0°C to +85°C
• High Input Sensitivity
• 800mV Minimum Peak–to–Peak Output Swing
• Differential PECL Outputs
