BCM94311
®
AIRFORCE 54G® 802.11A/B/G PCI EXPRESS® CLIENT REFERENCE DESIGN
FEATURES
•
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.
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.
•
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.
