BIPOLAR ANALOG + DIGITAL INTEGRATED CIRCUIT PB1007K 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 PB1007K is a silicon monolithic integrated circuit for GPS receiver. This IC is designed as double conversion RF block integrated Pre-Amplifier + RF/IF down-converter + PLL frequency synthesizer on 1 chip. This IC is lower current than the PB1005K and packaged in a 36-pin QFN package. This IC is manufactured using our 30 GHz fmax UHS0 (Ultra High Speed Process) silicon bipolar process. FEATURES Double conversion : fREFin = 16.368 MHz, f1stIFin = 61.380 MHz, f2ndIFin = 4.092 MHz Integrated RF block : Pre-Amplifier + RF/IF frequency down-converter + PLL frequency synthesizer 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 = 25.0 mA TYP. VCC = 3.0 V Gain adjustable externally : Gain control voltage pin (control voltage up vs. gain down) On-chip pre-amplifier : GP = 15.5 dB TYP. f = 1.57542 GHz NF = 3.2 dB TYP. f = 1.57542 GHz Power-save function : Power-save dark current ICC(PD) = 5 A MAX. High-density surface mountable : 36-pin plastic QFN APPLICATIONS Consumer use GPS receiver of reference frequency 16.368 MHz, 2nd IF frequency 4.092 MHz (for general use) ORDERING INFORMATION Part Number Package Supplying Form PB1007K-E1-A 36-pin plastic QFN 12 mm wide embossed taping Pin 1 indicates pull-out direction of tape Qty 2.5 kpcs/reel Remark To order evaluation samples, contact your nearby sales office.
