General Description

The Atheros AR9220 is a highly integrated single-chip solution for 2.4 and 5 GHz 802.11nready wireless local area networks (WLANs) that enables high-performance 2x2 MIMO configurations for wireless station applications demanding robust link quality and maximum throughput and range.

The AR9220 integrates a multi-protocol MAC, baseband processor, analog-to-digital and digital-to-analog (ADC/ DAC) converters, 2x2 MIMO radio transceiver, and PCI interface in an all-CMOS device for low power and small form factor applications.

The AR9220 implements half-duplex OFDM, CCK, and DSSS baseband processing, supporting up to 130 Mbps for 20 MHz and 300 Mbps for 40 MHz channel operations respectively, and IEEE 802.11a/b/g data rates.

Overview

Data Sheet October 2009 AR9220 Single-Chip 2x2 MIMO MAC/BB/Radio with PCI Interface for 802.11n 2.

Key Features

include signal detection, automatic gain control, frequency offset estimation, symbol timing, and channel estimation. The AR9220 MAC supports the 802.11 wireless MAC protocol, 802.11i security, receive and transmit filtering, error recovery, and quality of service (QoS). The AR9220 supports two simultaneous traffic streams using up to two integrated transmit chains and receive chains for high throughput and range performance. Transmit chains combine baseband in-phase (I) and quadrature (Q) signa.
