EVALUATION KIT AVAILABLE MAX2769 Universal GPS Receiver General Description Features GPS/GLONASS/Galileo Receivers The MAX2769 is the industrys first global navigation satellite system (GNSS) receiver covering GPS, No External IF SAW or Discrete Filters Required GLONASS, and Galileo navigation satellite systems on a Programmable IF Frequency single chip. This single-conversion, low-IF GNSS receiver Fractional-N Synthesizer with Integrated VCO is designed to provide high performance for a wide range Supports Wide Range of Reference Frequencies of consumer applications, including mobile handsets. Dual-Input Uncommitted LNA for Separate Designed on Maxims advanced, low-power SiGe Passive and Active Antenna Inputs BiCMOS process technology, the MAX2769 offers the 1.4dB Cascade Noise Figure highest performance and integration at a low cost. Integrated Crystal Oscillator Incorporated on the chip is the complete receiver Integrated Active Antenna Sensor chain, including a dual-input LNA and mixer, followed 10mA Supply Current in Low-Power Mode by the image-rejected filter, PGA, VCO, fractional-N frequency synthesizer, crystal oscillator, and a multibit 2.7V to 3.3V Supply Voltage ADC. The total cascaded noise figure of this receiver is Small, 28-Pin, RoHS-Compliant, Thin QFN Lead- as low as 1.4dB. Free Package (5mm x 5mm) The MAX2769 completely eliminates the need for external IF filters by implementing on-chip monolithic filters and Ordering Information requires only a few external components to form a com- plete low-cost GPS receiver solution. PART TEMP RANGE PIN-PACKAGE The MAX2769 is the most flexible receiver on the MAX2769ETI+ -40C to +85C 28 Thin QFN-EP* market. The integrated delta-sigma fractional-N frequency MAX2769E/W -40C to +85C Dice (In Wafer Form) synthesizer allows programming of the IF frequency within a 40Hz accuracy while operating with any refer- +Denotes a lead(Pb)-free/RoHS-compliant package. ence or crystal frequencies that are available in the *EP = Exposed paddle. 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 Pin Configuration/Block Diagram either at the CMOS logic or at the limited differential logic levels. Functional Diagrams The MAX2769 is packaged in a compact 5mm x 5mm, 28-pin thin QFN package with an exposed paddle. The 21 20 19 18 17 16 15 part is also available in die form.
