NECâs 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.
NECâs stringent quality assurance and test procedures ensure the highest reliability and performance.
