SEMICONDUCTOR TECHNICAL DATA 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. • • • • • • • MECL PLL COMPONENTS ÷256 PRESCALER 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 DESIGN GUIDE Criteria Value Unit Internal Gate Count* 62 ea Internal Gate Propagation Delay 250 ps Internal Gate Power Dissipation 10 mW Speed Power Product 2.5 pJ P SUFFIX 8–LEAD PLASTIC PACKAGE CASE 626–05 D SUFFIX 8–LEAD PLASTIC SOIC PACKAGE CASE 751–05 * Equivalent to a two–input NAND gate MAXIMUM RATINGS Symbol Characteristic VCC Power Supply Voltage TA Operating Temperature Range Tstg Storage Temperature Range Range Unit 7.0 Vdc 0 to +85 °C –65 to +175 °C Pinout: 8–Lead Plastic (Top View) Output VCC 8 7 6 1 2 3 NC 5 ELECTRICAL CHARACTERISTICS (VCC = 4.5 to 5.5V; TA = 0 to +85°C) Symbol Characteristic fmax1 fmin Toggle Frequency (Sine Wave Input) ICC Supply Current at 5.5V Vout Output Voltage (Load =10pF) Vin min Input Voltage 70MHz Sensitivity 150–1100MHz 1.2GHz 1.3GHz Vin max Input Overload 70–1300MHz Min Typ* 1.3 1.6 36 0.8 Max Unit 70 GHz MHz 50 mA 1.2 10 1.0 1.5 3.0 400 NC Input VPP 20 4.0 15 20 mVrms mVrms * Typical measured at +25°C, 5.0V 1.
