General Description
MAX2769
Universal GPS Receiver
Features
The MAX2769 is the industry’s first global navigation
satellite system (GNSS) receiver covering GPS,
GLONASS, and Galileo navigation satellite systems on a
single chip. This single-conversion, low-IF GNSS receiver
is designed to provide high performance for a wide range
of consumer applications, including mobile handsets.
Designed on Maxim ’s advanced, low-power SiGe
BiCMOS process technology, the MAX2769 offers the
highest performance and integration at a low cost.
Incorporated on the chip is the complete receiver
chain, including a dual-input LNA and mixer, followed
by the image-rejected filter, PGA, VCO, fractional-N
frequency synthesizer, crystal oscillator, and a multibit
ADC. The total cascaded noise figure of this receiver is
as low as 1.4dB.
The MAX2769 completely eliminates the need for external
IF filters by implementing on-chip monolithic filters and
requires only a few external components to form a com-

within a ±40Hz accuracy while operating with any refer-
ence or crystal frequencies that are available in the
host system. The integrated ADC outputs 1 or 2 quan-
tized bits for both I and Q channels, or up to 3 quan-
tized bits for the I channel. Output data is available
either at the CMOS logic or at the limited differential
logic levels.
