Atheros Communications Inc. introduces the AR9374 WiFi chip, which offers powerful wireless connectivity to fixed consumer electronics, enabling consumers to enjoy content everywhere in the home with connected TVs, set-top boxes, Blu-ray players, digital media adapters, home network-attached-storage, speakers, game consoles and wireless audio products. With an increased number of WiFi devices crowding the 2.4GHz band, consumers now need to leverage the 5GHz band for reliable media-rich applications that require interference-free bandwidth and less latency. The AR9374 chip also offers 40MHz transmissions to support high data rate applications without the limitations of range and costs associated with previous WiFi standards.

The introduction of this chip demonstrates Atheros' commitment to developing new and innovative WiFi technologies. With its technology portfolio and expertise in 5GHz radio development, Atheros is now delivering a highly integrated, single-chip solution capable of connecting multiple consumer electronics devices everywhere in the home.

The AR9374 is a single-chip dual-band 802.11n MIMO solution with integrated efficient power amplifiers (EPAs) and low noise amplifiers (LNAs) that enables reliable wireless connectivity and advanced streaming performance at similar prices as previous single-stream solutions, eliminating cost barriers for consumer electronics manufacturers to step up to more media-capable WiFi.

The AR9374 integrates powerful CPU and on-chip memory to offload all WLAN functions from the host processor, making it easier for consumer electronics manufacturers to incorporate high performance WiFi to connected TV designs. The chip achieves full host offload without the use of external memory, resulting in low total solution cost in the industry.

The AR9374 delivers up to 170Mbps of actual wireless throughput (300Mbps data rate) and a full complement of advanced 11n options (transmit beam forming, low density parity check, space-time block code, maximum ratio combine, and maximum likelihood detection receiver) to provide more robust rate-over-range, resulting in reliable wireless coverage for higher throughput applications.

The AR9374 solution incorporates advanced Atheros algorithms to assure robust delivery of video and audio streams in typical home networking environments.

The AR9374 features include an efficient sleep mode and wake-on-wireless mode to reduce system power consumption that addresses the increasingly strict energy regulations for TV manufacturers.

The AR9374 is the first in the industry to support both SDIO and USB HSIC, offering interface flexibility.

Samples of the AR9374 chip are now available.
