µPB1508GV is a 3.0 GHz input divide by 2 prescaler IC for DBS tuner applications. µPB1508GV can make VHF/UHF band PLL frequency synthesizer apply to DBS/ECS tuners. µPB1508GV is a shrink package version of µPB584G so that this small package contributes to reduce the mounting space.

µPB1508GV is 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, this IC has 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, 12 mA

• Fixed division : ÷2

APPLICATION

• Prescaler between local oscillator and PLL frequency synthesizer included modulus prescaler

• DBS tuners with kit use of VHF/UHF band PLL frequency synthesizer
