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 : 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

? Multiple system clocks : On-chip switchable frequency divider (1/N = 100, 3/256, 9/1024, 65/4096)

? A/D converter : On-chip 4-bit A/D converter

? High-density RF block : On-chip VCO tank circuit and 2ndIF filter
