Navigation receiver claims universal
application
The MAX2769E/W is the first navigation satellite system receiver to cover GPS (L1 C/A code and P-code), WAAS, Egnos, Galileo and Glonass navigation satellite systems.
Maxim Integrated Products reckons the MAX2769E/W is the industry's first universal, global navigation satellite system (GNSS) receiver for GPS (L1 C/A code and P-code), WAAS, Egnos, Galileo and Glonass navigation satellite systems in a single tested die As GPS baseband technology becomes more integrated into the host processor with lower geometry CMOS processes, the need for a high-performance external GPS RFIC becomes more essential

Speedy DAC claims dynamic superiority for comms
The MAX5195 is a 14bit 260Msample/s DAC claimed to provide the world's best dynamic performance in spurious-free dynamic range, intermodulation distortion and signal to noise ratio.
Low-power serial ADC runs up to 200Ksample/s
New from Maxim Integrated Products, the MAX1162 serial-interface 16bit A/D convertor connects directly to SPI, QSPI and Microwire devices without additional interface logic.
Fulfilling this need, the MAX2769E/W high-performance RFIC provides a total cascaded noise figure of 1.4dB and is designed for die-level integration into a single package.
Consequently, this receiver is ideal for a wide range of consumer applications, including automotive navigation, asset tracking, cellular handsets, portable navigation devices (PNDs), digital cameras, laptops and ultramobile personal computers (UMPCs).
Designed on Maxim's advanced, low-power SiGe BiCMOS process technology, the MAX2769E/W offers the industry's highest performance and integration at a low cost.
Incorporated on the chip is a complete receiver chain, including a dual-input LNA and mixer, followed by an image-rejected filter, VGA, VCO, fractional-N frequency synthesiser, crystal oscillator, and a multibit ADC.
Through this high level of integration, the MAX2769E/W eliminates the need for external IF SAW filters, as well as an external LNA in passive antenna applications.
Consequently, it requires only a few external components to form a complete, low-cost GPS receiver solution.
The MAX2769E/W is the most flexible receiver on the market.
The integrated delta-sigma fractional-N frequency synthesiser allows IF programming with +/-40Hz accuracy while operating with any reference or crystal frequency available in the host system.
The on-chip ADC outputs one or two quantised bits for both I and Q channels, or three quantised bits for the I channel.
Output data is available either at CMOS or limited-differential logic levels.
The MAX2769E/W is designed to work with virtually all GPS baseband processors on the market.
Fully specified for operation over the -40 to +85C extended temperature range, the MAX2769E/W is available in a single tested-die, wafer-level (by request only), and 28-pin TQFN packages.
Prices start at US $2.95 (1000-up).
