7V to 3.
3V Supply Voltage Small, 28-Pin, RoHS-Compliant, Thin QFN LeadFree Package (5mm x 5mm) MAX2769 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...
