NEC’s 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.
NEC’s stringent quality assurance and test procedures ensure the highest reliability and performance.
