AIRFORCE 54G® 802.11A/B/G PCI EXPRESS® CLIENT REFERENCE DESIGN

FEATURES

POWER MANAGEMENT

• IEEE 802.11a/g CMOS MAC/Baseband client solution with

BroadRange™ for PCI Express® conections. Flexible design provides an

802.11b/g or 802.11a/g solution when paired with an appropriate radio.

• Supports Wireless Form Factor (WFF) PCI Express cards for desktop

PCs, Wireless on Motherboard (WOMBO) notebook modules, and

embedded Wi-Fi® applications for 54g® to PCI Express connections.

• High-speed serial bus supports x1 lane running at 2.5 Gbps in each

direction for improved Quality of Service (QoS), Error Detection, Power

Management, Hot Plug/Hot Swap capability, and simplified board layout.

• Includes BroadRange signal processing for industry-leading receive

sensitivity and extended range.

• Highly integrated chipset provides low cost, low power, and small

footprint for integration in a broad range of devices.

• WHQL-certified drivers for Windows® XP, Windows® Me, Windows®

2000, Windows® 98SE, and Windows® 98 operating systems, portable to

Linux® and Windows® CE.

• USB 1.1 host for expanded Bluetooth® connectivity and coexistence.

• 4-KB one-time programmable (OTP) memory for customer-defined

parameters.

• Industry-standard UART and JTAG interfaces to manage other serial

devices for in-system testing.

• On-chip 1.8V/2.5V regulators reduce component cost and power

dissipation and simplify PCB design.

• DSP architecture reduces the power required to transmit data by 30%.

• Low-power consumption improves battery life of Wi-Fi devices,

including handheld devices and consumer electronics.

• Meets PCI Power Management Interface version 1.1 (ACPI).

• Designed for low CPU usage to ensure these CPU resources are

available for handheld applications.

• DynamAicIpRowFer mOanRageCmeEnt unFdeEr dAriveTr cUontRrol.E S E T

• SmartRadio™: Continuous calibration reduces test time and improves

manufacturability.

• Xpress™ Technology: Standards-based frame bursting improves

overall network efficiency.

• 125 High Speed Mode™: Standards-plus performance enhancement

delivers best real-world performance when both client and AP support

high speed mode.

• BroadRange Technology: Standards-compliant feature increases

receive sensitivity to improve range at the higher data rates.

• Security:

- WPA- and WPA2-CERTIFIED™ for powerful encryption and

authentication.

- AES in hardware for faster data encryption and 802.11i compatibility

- Cisco® Compatible Extensions (CCX, CCX 2.0) certified

- SecureEasySetup™ for simple Wi-Fi setup and WPA security

configuration

• Worldwide support: Global products supported with worldwide

homologated design.
