Universal GPS ReceiverImprove GPS and GALILEO Performance and Reduce Cost with the First Fully Programmable, Universal GNSS RF Receiver
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 complete low-cost GPS receiver solution.
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.
