| BCM94311 (R) AIRFORCE 54G(R) 802.11A/B/G PCI EXPRESS(R) CLIENT REFERENCE DESIGN FEATURES * IEEE 802.11a/g CMOS MAC/Baseband client solution with BroadRangeTM for PCI Express(R) conections. Flexible design provides an 802.11b/g or 802.11a/g solution when paired with an appropriate radio. POWER MANAGEMENT * 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. * 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. (R) (R) * Meets PCI Power Management Interface version 1.1 (ACPI). * Designed for low CPU usage to ensure these CPU resources are available for handheld applications. * 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. * Dynamic power management under driver control. AIRFORCE FEATURE SET * SmartRadioTM: Continuous calibration reduces test time and improves manufacturability. * 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. * XpressTM Technology: Standards-based frame bursting improves overall network efficiency. * WHQL-certified drivers for Windows(R) XP, Windows(R) Me, Windows(R) 2000, Windows(R) 98SE, and Windows(R) 98 operating systems, portable to Linux(R) and Windows(R) CE. * 125 High Speed ModeTM: 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. * USB 1.1 host for expanded Bluetooth(R) connectivity and coexistence. * 4-KB one-time programmable (OTP) memory for customer-defined parameters. * Security: WPA- and WPA2-CERTIFIEDTM for powerful encryption and authentication. AES in hardware for faster data encryption and 802.11i compatibility Cisco(R) Compatible Extensions (CCX, CCX 2.0) certified SecureEasySetupTM for simple Wi-Fi setup and WPA security configuration * 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. * Worldwide support: Global products supported with worldwide homologated design.
