UPB1506GV

DATA SHEET BIPOLAR DIGITAL INTEGRATED CIRCUITS PPB1506GV, PPB1507GV 3GHz INPUT DIVIDE BY 256, 128, 64 PRESCALER IC FOR ANALOG DBS TUNERS The PPB1506GV and PPB1507GV are 3.0 GHz input, high division silicon prescaler ICs for analog DBS tuner applications. These ICs divide-by-256, 128 and 64 contribute to produce analog DBS tuners with kit-use of 17 K series DTS controller or standard CMOS PLL synthesizer IC. The PPB1506GV/PPB1507GV are shrink package versions of the PPB586G/588G or PPB1505GR so that these smaller packages contribute to reduce the mounting space replacing from conventional ICs. The PPB1506GV and PPB1507GV are manufactured using NEC’s high fT NESAT™IV silicon bipolar process. This process uses silicon nitride passivation film and gold electrodes. These materials can protect chip surface from external pollution and prevent corrosion/migration. Thus, these ICs have excellent performance, uniformity and reliability. FEATURES x x x x x High toggle frequency Low current consumption Selectable high division Pin connection variation : fin = 0.5 GHz to 3.0 GHz : 5 V, 19 mA : y256, y128, y64 : PPB1506GV and PPB1507GV High-density surface mounting : 8-pin plastic SSOP (175 mil) APPLICATION These ICs can use as a prescaler between local oscillator and PLL frequency synthesizer included modulus prescaler. For example, following application can be chosen; x x Analog DBS tuner’s synthesizer Analog CATV converter synthesizer ORDERING INFORMATION PART NUMBER PACKAGE 8...
