BIPOLAR DIGITAL INTEGRATED CIRCUITS
PB1507GV
3GHz INPUT DIVIDE BY 256, 128, 64 PRESCALER IC
FOR ANALOG DBS TUNERS
The PB1507GV has 3.0 GHz input, high division silicon prescaler ICs for analog DBS tuner applications. This IC
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.
ICs.
The PB1507GV are manufactured using the high f
T
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.
The
PB1507GV is a shrink package version of the
PB586G/588G or
PB1505GR so that these smaller packages contribute to reduce the mounting space replacing from conventional
