MAX2769B

Universal GPS Receiver

General Description

Features

The MAX2769B is a next-generation Global Navigation

SatelliteSystem(GNSS)receivercoveringGPS,GLONASS,

Galileo, and Compass navigation satellite systems on

a single chip. This single-conversion GNSS receiver is

designed to provide high performance for industrial and

automotive applications.

S AEC-Q100 Automotive Qualified

S GPS/GLONASS/Galileo/Compass Systems

S 40pF Output Clock Drive Capability

S No External IF SAW or Discrete Filters Required

S Programmable IF Frequency

Designed on Maxim’s advanced, low-power SiGe BiCMOS

process technology, the MAX2769B 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.

S Fractional-N Synthesizer with Integrated VCO

Supports Wide Range of Reference Frequencies

S Dual-Input Uncommitted LNA for Separate Passive

and Active Antenna Inputs

S 1.4dB Cascade Noise Figure

S Integrated Crystal Oscillator

S Integrated Active Antenna Sensor

S 2.7V to 3.3V Supply Voltage

The MAX2769B completely eliminates the need for exter-

nal IF filters by implementing on-chip monolithic filters

and requires only a few external components to form a

complete low-cost GPS RF receiver solution.

S Small, 28-Pin, RoHS-Compliant, Thin QFN Lead-

Free Package (5mm x 5mm)

The MAX2769B is the most flexible receiver on the mar-

ket. The integrated delta-sigma fractional-N frequency

synthesizer allows programming of the IF frequency

ing with any reference or crystal frequencies that are

available in the host system. The ADC outputs CMOS

logic levels with 1 or 2 quantized bits for both I and Q

channels, or up to ± quantized bits for the I channel. I and

Q analog outputs are also available.

The MAX2769B is packaged in a 5mm x 5mm, 28-pin thin

QFN package with an exposed paddle.
