Datasheet for Qualcomm Atheros AR9374

2.4/5 GHz 2-stream dual-band-selectable 802.11n WLAN solution for USB and Embedded CE Applications.

Product Overview
The AR9374 UB134 is the industry’s most advanced solution for adding 2x2 dual-band 802.11n WLAN connectivity to a range of USB connectivity or embedded CE applications. Some of the ideal applications include Digital TVs, Blu-Ray Players, Digital Media Adapters, Home Network-Attached-Storage, Wireless Audio, and a range of others. The AR9374 single-chip WLAN solution leverages Qualcomm industry leadership in all-CMOS radio design. AR9374 is a highly-integrated single-chip delivering high performance 2x2 MIMO configurations in both 2.4 GHz and 5 GHz bands and offering robust link quality, maximum throughput and highest range. With its very small package footprint and low power consumption it enables WLAN connectivity in a new set of use-cases.
AR9374 integrates into a single chip a powerful full-offload CPU with a complete on-chip memory subsystem including ROM and RAM. This solution eliminates the need for external memory components and enables ultra-low-cost and small-form-factor embedded WLAN designs. With its powerful CPU and memory subsystem, the AR9374 enables integration of WLAN into systems where the host CPU lacks headroom to support WLAN processing. The AR9374 also integrates on-chip the complete MAC, Baseband and Radio as well as the industry’s highest performing on-chip CMOS PAs (Power Amplifiers) and LNAs (Low Noise Amplifiers). It also includes on-chip memory and peripherals to enable a host of advanced WLAN applications including streaming audio, streaming video, and direct ad-hoc peer-to-peer wireless connections.
