EVALUATION KIT AVAILABLE MAX2769B Universal GPS Receiver General Description Features The MAX2769B is a next-generation Global Navigation S AEC-Q100 Automotive Qualified Satellite System (GNSS) receiver covering GPS, GLONASS, S GPS/GLONASS/Galileo/Compass Systems Galileo, and Compass navigation satellite systems on S 40pF Output Clock Drive Capability a single chip. This single-conversion GNSS receiver is S No External IF SAW or Discrete Filters Required designed to provide high performance for industrial and automotive applications. S Programmable IF Frequency Designed on Maxims advanced, low-power SiGe BiCMOS S Fractional-N Synthesizer with Integrated VCO process technology, the MAX2769B offers the highest Supports Wide Range of Reference Frequencies performance and integration at a low cost. Incorporated S Dual-Input Uncommitted LNA for Separate Passive on the chip is the complete receiver chain, including a and Active Antenna Inputs dual-input LNA and mixer, followed by the image-rejected S 1.4dB Cascade Noise Figure filter, PGA, VCO, fractional-N frequency synthesizer, crystal oscillator, and a multibit ADC. The total cascaded S Integrated Crystal Oscillator noise figure of this receiver is as low as 1.4dB.
