GPS chip covers Galileo and Glonass too
Universal single-chip global navigation satellite system receiver covers GPS, Galileo and Glonass navigation satellite systems.
New from Maxim Integrated Products, the MAX2769 is billed as the industry's first universal, single-chip global navigation satellite system (GNSS) receiver for GPS (L1 C/A code and P-code), Galileo and Glonass navigation satellite systems Due to integration of a complete receiver chain, including an LNA, this receiver eliminates the need for an external LNA and achieves a total cascaded noise figure (NF) of 1.4dB

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.
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.
The MAX2769 is ideal for a wide range of applications including automotive navigation, asset tracking, cellular handsets, portable navigation devices (PNDs), digital cameras, laptops, and ultra-mobile personal computers (UMPCs).
Designed using Maxim's advanced, low-power SiGe BiCMOS process technology, the MAX2769 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, image-rejected filter, VGA, VCO, fractional-N frequency synthesiser, crystal oscillator and multibit ADC.
Through this high level of integration, the MAX2769 eliminates the need for an external LNA in passive antenna applications and also the need for external IF SAW filters.
Consequently, it requires only a few external components to form a complete low-cost GPS receiver solution that achieves a total cascaded NF as low as 1.4dB.
The MAX2769 is the most flexible receiver on the market.
The integrated delta-sigma fractional-N frequency synthesiser enables IF-programming with +/-40Hz accuracy while operating with any reference or crystal frequency that is available in the host system.
The integrated 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 at limited-differential logic levels.
The MAX2769 is designed to work with most GPS baseband processors on the market.
The MAX2769 is specified for operation over the -40 to +85C temperature range.
This receiver is packaged in a compact, 5 x 5mm, 28-pin TQFN with an exposed paddle; a tested die version is also available.
1000-up prices start at US $2.95.
