1. General

The Qualcomm Atheros AR9582  is a highly integrated single-chip  solution for 5 GHz

802.11n wireless local  area networks (WLANs) that enables  high-performance 2x2 MIMO  with 2

Spatial Streams for  wireless applications demanding  the highest robust link quality  and maximum

throughput and range.  The AR9582 integrates a multi-protocol  MAC, baseband processor, analogto-

digital/digital-to-analog  converters (ADC/DAC), 2x2  MIMO radio transceivers, and  PCI

Express interface  in an all-CMOS device for low  power consumption and small  form-factor

applications.

The AR9582 implements  half-duplex OFDM, CCK, and  DSSS baseband process, supporting  up to

150 Mbps for 20 MHz  and 300 Mbps for 40 MHz  channel operations, and IEEE 802.11a/b/g

data rates. Additional features  include Maximal Likelihood  (ML) decoding, Low-Density  Parity

Check (LDPC), Maximal  Ratio Combining (MRC), Tx  Beamforming (TxBF), Space  Time Block

Code (STBC), and  On-Chip One-Time Programmable  (OTP) memory. The AR9582

supports

802.11 wireless MAC  protocol, 802.11i security, Rx/Tx filtering,  error recovery, and 802.11e

quality of service  (QoS).

The AR9582 supports up  to two simultaneous traffic streams  integrating two Tx and two Rx

chains for high throughput  and extended coverage. Tx  chains combine baseband in-phase  (I) and

quadrature (Q) signals,  convert them to the desired  frequency, and drive the RF signal to  multiple

antennas. Rx chains  use an integrated architecture. The  frequency synthesizer supports  1-MHz

steps to match frequencies  defined by IEEE 802.11a/  g/n specifications.

The AR9582 supports frame  data transfer to and from the  host using a PCIE interface providing

interrupt generation  and reporting, power save, and  status reporting. Other external  interfaces

include EEPROM.
