SEMICONDUCTOR TECHNICAL DATA 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. • • • • • • MECL PLL COMPONENTS ÷256 PRESCALER 1.1GHz Toggle Frequency Operating Supply Voltage of 4.5 to 5.5V Low–Power 23mA Typical at VCC = 5.0V High Input Sensitivity, 20mVrms at VCC = 5.0 ± 10%, TA = 0°C to +70°C 800mV Minimum Peak–to–Peak Output Swing Differential PECL Outputs MAXIMUM RATINGS Symbol Characteristic VCC Power Supply Voltage TA Operating Temperature Range Tstg Storage Temperature Range Range Unit 7.0 Vdc 0 to +70 °C –65 to +175 °C ELECTRICAL CHARACTERISTICS (VCC = 4.5 to 5.5V; TA = 0 to +70°C) Symbol Characteristic Min Typ* fmax1 fmin Toggle Frequency (Sine Wave Input) 1.1 1.3 ICC Supply Current at 5.5V Vout Output Voltage (Load =10pF) Vin min Input Voltage Sensitivity 150–1100MHz 90MHz Vin max Input Overload * Typical measured at +25°C, 5.0V 1.
