| Wireless Data and Networking Components WLAN 802.11 Single-Chip WLAN 802.11b Baseband/MAC CX85410 First In A Family of Highly Integrated WLAN Solutions Conexant's broadband communications portfolio includes a comprehensive suite of semiconductor solutions that enable the digital home and information network. Now, with the CX85410, WLAN system providers can bring to market secure, low-cost products that meet tomorrow's WLAN needs today. The highly integrated CX85410 Baseband/MAC 802.11b can be offered as a stand-alone device, or used in conjunction with Conexant's home network processor, ADSL and cable modem semiconductor system solutions. The device supports data rates up to 11 Mbps, with automatic fallback to 5.5, 2 and I Mbps when needed and is compatible with existing IEEE 802.11b modulation schemes. The advanced radio interface with automatic gain control (ACG) supports multiple 2.4 GHz radios while the antenna diversity, which allows for multiple antennas in a system, continually monitors for the strongest signal. Unique to the CX85410 is the necessary on-chip support to manage industry security standards including the Wired Equivalent Privacy (WEP) 64 and 128-bit standard, the Wi-Fi Protected AccessTM (WPA) and the full IEEE 802.11i standard. Other Baseband/MAC offerings require hardware upgrades for this level of support. The CX85410 also contains on-chip SRAM, eliminating the need for external memory which results in further reducing the layout size and system cost. These features ensure designers the ability to create small footprint, single-sided designs resulting in lower overall system manufacturing costs. For manufacturers of network interface cards, a variety of host interfaces are supported including PCI 2.2/2.3, MiniPCI and 32-bit Cardbus. All of these features can lead to increased throughput, greater range and an overall robust and lower cost WLAN solution.
