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.
