DESCRIPTION

The

µPB1005K is a silicon monolithic integrated circuit for GPS receiver. This IC is designed as double

conversion RF block integrated RF/IF down-converter + PLL frequency synthesizer on 1 chip.

The

µPB1005K features 36-pin plastic QFN, fixed prescaler and supply voltage. The 36-pin plastic QFN package

is suitable for high density surface mounting. The fixed division internal prescaler is needless to input serial counter

data.

Supply voltage is 3 V.

Thus, the

µPB1005K can make RF block fewer components and lower power

consumption.

silicon nitride passivation film and gold electrodes. These materials can protect the chip surface from pollution and

prevent corrosion/migration. Thus, this IC realizes excellent performance, uniformity and reliability.

FEATURES

• Double conversion

• Integrated RF block

: RF/IF frequency down-converter + PLL frequency synthesizer

• High-density surface mountable : 36-pin plastic QFN (6.0

× 6.0 × 0.95 mm)

• Needless to input counter data : fixed division internal prescaler

• VCO side division

:

÷ 200 (÷ 25, ÷ 8 serial prescaler)

• Reference division

:

÷ 2

• Supply voltage

• Low current consumption

• Gain adjustable externally

: Gain control voltage pin (control voltage up vs. gain down)

APPLICATION

• Consumer use GPS receiver of reference frequency 16.368 MHz, 2nd IF frequency 4.092 MHz
