UPB1009K

NEC’s LOW POWER GPS RF RECEIVER BIPOLAR ANALOG + INTEGRATED CIRCUIT UPB1009K DESCRIPTION The µPB1009K is a silicon monolithic IC developed for GPS receivers. This IC integrates a full VCO, second IF filter, 4-bit ADC, and digital control interface to reduce cost and mounting space. In addition, its power consumption is low. Moreover, use of a TCXO with frequency of 16.368 MHz/16.384 MHz, 14.4 MHz, 19.2 MHz, or 26 MHz switchable with an on-chip divider is possible. NEC’s stringent quality assurance and test procedures ensure the highest reliability and performance. FEATURES Double conversion Multiple system clocks A/D converter High-density RF block Supply voltage Low current consumption High-density surface mountable : fREFin = 16.368 MHz, f1stIFin = 61.380 MHz, f2ndIFin = 4.092 MHz : fREFin = 14.4, 16.384, 19.2, 26 MHz, f1stIFin = 62.980 MHz, f2ndIFin = 2.556 MHz : On-chip switchable frequency divider (1/N = 100, 3/256, 9/1024, 65/4096) : On-chip 4-bit A/D converter : On-chip VCO tank circuit and 2ndIF filter : VCC = 2.7 to 3.3 V : ICC = 26.0 mA TYP. @ VCC = 3.0 V, N = 100 : 44-pin plastic QFN APPLICATIONS Consumer use GPS receiver of reference frequency 16.368 MHz, 2nd IF frequency 4.092 MHz Consumer use GPS receiver of reference frequency 14.4, 16.384, 19.2, 26 MHz, 2ndIF frequency 2.556 MHz Caution Observe precautions when handling because these devices are sensitive to electrostatic discharge.
