PRELIMINARY DATA SHEET  
BIPOLAR ANALOG + DIGITAL INTEGRATED CIRCUIT  
µPB1005K  
REFERENCE FREQUENCY 16.368 MHz, 2ND IF FREQUENCY 4.092 MHz  
RF/IF FREQUENCY DOWN-CONVERTER +  
PLL FREQUENCY SYNTHESIZER IC FOR GPS RECEIVER  
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.  
This IC is manufactured using NEC’s 20 GHz fT NESATTMIII silicon bipolar process. This process uses direct  
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  
: fREFin = 16.368 MHz, f2ndIFout = 4.092 MHz  
: 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  
• Reference division  
Supply voltage  
: ÷ 200 (÷ 25, ÷ 8 serial prescaler)  
: ÷ 2  
: VCC = 2.7 to 3.3 V  
Low current consumption  
Gain adjustable externally  
: ICC = 45.0 mA TYP.@VCC = 3.0 V  
: 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
