The MAX2769 is the most flexible receiver on the market. The integrated delta-sigma fractional-N frequency synthesizer allows programming of the IF frequency within a ±40Hz accuracy while operating with any reference or crystal frequencies that are available in the host system. The integrated ADC outputs 1 or 2 quantized bits for both I and Q channels, or up to 3 quantized bits for the I channel. Output data is available either at the CMOS logic or at the limited differential logic levels. The MAX2769 is packaged in a compact 5mm x 5mm, 28-pin thin QFN package with an exposed paddle. The part is also available in die form. Contact the factory for further information. o GPS/GLONASS/Galileo Receivers No External IF SAW or Discrete Filters Required Programmable IF Frequency Fractional-N Synthesizer with Integrated VCO Supports Wide Range of Reference Frequencies Dual-Input Uncommitted LNA for Separate Passive and Active Antenna Inputs 1.4dB Cascade Noise Figure Integrated Crystal Oscillator Integrated Active Antenna Sensor 10mA Supply Current in Low-Power Mode 2.7V to 3.3V Supply Voltage Small, 28-Pin, RoHS-Compliant, Thin QFN LeadFree Package (5mm x 5mm) ADC 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.
