STA5630
Features
Integrated LNA
Low power consumption (< 25 mW)
1.8 V supply voltage
GPS and Galileo compliant
Minimum external components
Serial interface
3 bits A/D converter
CMOS 65 nm technology
2 kV HBM ESD protected
Standard QFN-32 package
Description
The chip is a fully integrated RF front-end able to
down-convert either the GPS L1 signal from
1575.42 MHz to 4.092 MHz.
The STA5630 embeds high performance LNA
minimizing external component count. The chip
uses state of the art CMOS 65 nm technology.
A 3-bit ADC converts the IF signal to Sign (SIGN)
and Magnitude (MAG0 and MAG1). The
magnitude bits are internally integrated in order to
control the variable gain amplifiers. The VGA gain
can be also set by the SPI interface.

Data brief
VFQFPN32
The STA5630 accepts a range of reference clocks
(10 to 52 MHz) and generates a 16.368 MHz
sampling clock (GPS_CLK) for the baseband. The
STA5630 embeds LDO to supply the internal core
of the device facilitating requirements to external
power supply.
High performance low power and cost effective
device, the STA5630 is the ideal solution for
automotive, cellular and consumer battery
powered applications.
