UPB1009K Datasheet | NEC

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 : f REFin = 16.368 MHz, f1st IFin = 61.380 MHz, f2nd IFin = 4.092 MHz : f REFin = 14.4, 16.384, 19.2, 26 MHz, f1st IFin = 62.980 MHz, f2nd IFin = 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 2nd IF filter : VCC = 2.7 to 3.3 V : ICC = 26.0 m A 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, 2nd IF frequency 2.556 MHz Caution Observe precautions when handling because these devices are sensitive to electrostatic discharge.
