The Cirrus CS22230 Wireless Mini PCI Controller incorporates the IEEE 802.11b media access controller (MAC) to enable Wi-Fi compliant wireless network devices providing industry-wide interoperability. In addition, the CS22230 supports our multimedia and quality of service (QoS) extensions to distribute entertainment content wirelessly throughout the home network - with unparalleled performance.
High Speed Wireless Network Internet Connections
The Cirrus CS22230 Wireless Mini PCI Controller enables high performance, reliable, embedded wireless network interface connections (NICs) for mobile devices, such as PC notebooks and web pads that utilize a Mini PCI form factor interface. The CS22230 delivers an optimal level of flexibility in cost, functionality, and performance. It is a highly integrated, single chip device that provides 11 Mbps wireless connectivity. On-chip interfaces include Mini PCI and high speed digital 802.11b wireless radio. The CS22230 also includes an embedded ARM7TDMI processor for executing networking protocols and network management functions. This programmable architecture enables a firmware upgrade path to new features and to track changes in standards specifications.

Reliable Wireless Multimedia
The Cirrus CS22230 integrates state-of-the-art Forward Error Correction (FEC) to enable high performance and reliable wireless networking. Unlike other error detecting mechanisms, FEC actually improves throughput by correcting corrupted data "on the fly." This is essential for multi-media applications, since retransmission would disrupt the user experience. The CS22230 includes a digital wireless radio MAC supporting a transmission rate of 11 Mbps. The radio MAC provides the necessary hardware functions for interfacing with low cost 11 Mbps digital radio PHY circuits. The CS22230 is designed to operate with Cirrus' WhitecapTM2 network protocol, which addresses the requirements for wireless distribution of high speed data as well as entertainment content (video, audio, and voice). Whitecap2 establishes a highly efficient, reliable, and easy to use wireless network that is compliant and interoperable with the Wi-Fi (802.11b) high speed wireless industry standard. Additionally, Whitecap2 is backward-compatible with previous versions of Whitecap and provides all the advanced functionality necessary to distribute entertainment throughout the wireless network.
