MAX2769B:Universal GPS Receiver

High-Performance, Automotive Grade GPS, GLONASS, Galileo, and Compass RF Receiver

The MAX2769B is a next-generation Global Navigation Satellite System (GNSS) receiver covering GPS, 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. 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. The MAX2769B 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 RF receiver solution. The MAX2769B is the most flexible receiver on the market. The integrated delta-sigma fractional-N frequency synthesizer allows programming of the IF frequency within a ±30Hz (fXTAL = 32MHz) accuracy while operating 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 3 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.
