DESCRIPTION
The µPB1005GS 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 µPB1005GS features shrink package, fixed prescaler and supply voltage. The 30-pin plastic SSOP 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 µPB1005GS can make RF block fewer components and lower power consumption.

FEATURES
• Double conversion : fREFin= 16.368 MHz, f2ndIFout= 4.092 MHz
• Integrated RF block : RF/IF frequency down-converter + PLL frequency synthesizer
• High-density surface mountable : 30-pin plastic SSOP (9.85 ×6.1 ×2.0 mm)
• Needless to input counter data : fixed division internal prescaler
  • VCO side division : ÷200 (÷25, ÷8 serial prescaler)
  • Reference division : ÷2
• Supply voltage : VCC= 2.7 to 3.3 V
• Low current consumption : ICC= 45.0 mA TYP.@VCC= 3.0 V
• 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
