1 / 3 page MOTOROLA SEMICONDUCTOR TECHNICAL DATA 1 REV 1 © Motorola, Inc. 1996 7/93 1.1GHz Prescaler 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. • 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 Range Unit VCC Power Supply Voltage 7.0 Vdc TA Operating Temperature Range 0 to +70 °C Tstg Storage Temperature Range –65 to +175 °C ELECTRICAL CHARACTERISTICS (VCC = 4.5 to 5.5V; TA = 0 to +70°C) Symbol Characteristic Min Typ* Max Unit fmax1 fmin Toggle Frequency (Sine Wave Input) 1.1 1.3 90 GHz MHz ICC Supply Current at 5.5V 23 30 mA Vout Output Voltage (Load =10pF) 0.8 1.2 VPP Vin min Input Voltage Sensitivity 150–1100MHz 90MHz 10 20 30 mVrms Vin max Input Overload 200 400 mVrms * Typical measured at +25 °C, 5.0V 1.
