PB1507GV
3GHz INPUT DIVIDE BY 256, 128, 64 PRESCALER IC
FOR ANALOG DBS TUNERS
Document No. P10767EJ3V0DS00 (3rd edition)
Date Published January 1998 N CP(K)
The
μ
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. The
μ
PB1507GV is a shrink package version of the
μ
PB586G/588G or
μ
PB1505GR so that these smaller packages contribute to reduce the mounting space replacing from conventional
ICs.
The
μ
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.
FEATURES
• High toggle frequency : fin = 0.5 GHz to 3.0 GHz
• High-density surface mounting : 8-pin plastic SSOP (175 mil)
• Low current consumption : 5 V, 19 mA
• Selectable high division : ÷256,÷128,÷64
• Pin connection variation :
μ
PB1507GV
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;
• Analog DBS tuner’s synthesizer
• Analog CATV converter synthesizer

NOTE CORRECT USE
(1) Observe prec autions for handling because of electro-static sensitive device s .
(2) Form a groun d pattern as wide as possible to minimize gro und impedance (to prevent undesired operation).
(3) Keep the wiring length of the ground pins as short as possible.
(4) Connect a bypass capacitor (e.g. 10 000 pF) to the VCC pin.
