UPB1009K-E1-A【PDF 1/28 页】IC GPS RECEIVER LP 44-QFN

NEC’s LOW POWER

GPS RF RECEIVER

BIPOLAR ANALOG + INTEGRATED CIRCUIT

UPB1009K

DESCRIPTION

The μ PB1009K 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.
