Based on eRide s proprietary GPS DSP architecture 1/2 ADC DESCRIPTION APPLICATIONS E911 ENABLED MOBILE PHONE NEC s UPB1008K is a Silicon RFIC especially designed for handheld low power/low cost GPS receivers. The IC com- IN-VEHICLE NAVIGATION SYSTEMS bines an LNA, followed by a double-conversion RF/IF LOW POWER HANDHELD GPS RECEIVER downconverter block and a PLL frequency synthesizer on one PC/PDA+GPS INTEGRATION chip. The second IF Freqency is a pseudo- baseband signal ASSET TRACKING into a on-chip 2-bit A/D converters.The device can operate on a supply voltage as low as 2.7 V, and is a housed in a small 36 pin QFN (Quad, Flat, No-lead) package, resulting in a very low power consumption and reduced board space. NEC s stringent quality assurance and test procedures en- sure the highest reliability and performance.
