BCM4322
Intensi-fi® Single-Chip 802.11n Transceiver

The BCM4322 is the world's first single-chip 802.11n solution. Designed using 65 nanometer CMOS processes, the BCM4322 combines all of the elements of a wireless LAN (WLAN) subsystem -- including power amplifiers -- onto a single silicon die. As a result of this unprecedented integration, the new Intensi-fi® solution is half the size of previous solutions and can reduce manufacturing costs by up to 40 percent.

In addition, the BCM4322 is the first solution to enable Wi-Fi™ products to achieve over 200 Megabits per second (Mbps) of actual wireless throughput to support several simultaneous multimedia applications.

	Features

• Single-chip all-in-one die Baseband/MAC/Radio for 2x2 802.11n applications


• 802.11n Draft 2.0 compliant Wi-Fi solution. Fully compatible with IEEE 802.11n Draft 1.0 and 802.11a/b/g legacy devices.


• Single-chip 65nm solution and high system integration drives down the cost of 802.11n solutions to enable a new generation of media/consumer applications


• CMOS integration and low power modes results in a 50% power reduction compared to previous generation solutions
