Conexant Systems announced a low-power, small form factor 802.11g radio chip for embedded mobile applications. The single-chip device is targeted at high performance, battery operated mobile devices such as multimedia cellular phones, enterprise handsets, PDAs, and digital cameras. The chip is shipping in volume quantities to customers now, and has been designed into several handset models by one the world’s largest cellular telephone manufacturers. A hardware and software reference design is also available to enable manufacturers and system integrators to rapidly integrate wireless connectivity into mobile platforms.
Conexant’s standards-compliant chip is a fully integrated wireless radio that includes a zero intermediate frequency (ZIF) transceiver, radio frequency (RF) synthesizer/voltage-controlled oscillator (VCO), high-speed data converters, ARM9-based media access controller (MAC), orthogonal frequency division multiplexing/complementary code key (OFDM/CCK) digital baseband processor, and a complete power management unit (PMU). Host control is provided by a flexible serial peripheral interface (SPI) supporting bit rates of 48 Mbps. http://www.conexant.com
