It provides a complete PRISM 2.5 reference design evaluation platform of hardware and software to system providers or integrators requiring wireless data communications capability and is ideal for integration into computer platforms. The Evaluation kit (ISL37300P-EVAL) includes two WLAN PC Cards designed to Intersil’s Prism reference design, Microsoft Windows® Driver, Local Area Network evaluation software, Prism Test Utilities (PTU) software and documentation to complete the evaluation. It supports the IEEE 802.11b network specification for Direct Sequence Spread spectrum DSSS signaling, providing data rates of 1, 2, 5.5, and 11 Mbps. Evaluation kit software updates are available on the Intersil Web Site. Access Points will be available from a number of suppliers, enabling a totally wireless network solution. Typical operating ranges are shown in Table 1.. Features • FCC Certified Under Part 15 to Operate in 2.4GHz ISM Band (Approval Pending) • Support for 11, 5.5, 2 and 1 Megabit Per Second (Mbps) Data Rates • Supports the lEEE 802.11 Direct Sequence Specification • Driver Supports Microsoft® Windows® 95, 98, 98SE, 2000, NT and ME • Supports Dual Diversity Antennas • Advanced RAKE Receiver Design with AGC • Provides Wireless Data Communications at Full Ethernet Speed • Designed to Fully Support PC-card Defined Mechanical and Environmental Stress Conditions • Intelligent Power Control, Including IEEE 802.11 Power Save Mode • Complete Reference Design, the ISL37300P CD is available to ensure Minimum Time-to-Market NOTES: 1. Throughout this document, all references to ‘PC Card’, ‘WLAN adapter’, ‘adapter’, or ‘card’ refer to a card assembly conforming to the mechanical size specifications of the PC Card. 2. The range will vary in different operating environments due to effects such as building construction. 3. At present, PTTU supports Windows 95, 98 and 98SE.

The card will also operate on channels 12 through 14, where permitted by local regulatory authorities. Radio equipment must be certified in a country prior to use. Refer to Table 4 for a list of countries and agencies that have approved the ISL37300P-EVAL for operation. The Intersil PRISM Chip Set allows for high level integration for reduced size, increased throughput, improved radio performance and faster time to market. The WLAN PC-card implements Direct Sequence Spread Spectrum DSSS technology providing superior noise and signal jamming immunity including less severe impact from unintentional radiators such as microwave ovens. The user can connect the PC-card in an ad-hoc peer to peer networking scheme, allowing for instant network setup in any office environment. By using an access point, the wireless LAN can be set up to allow for a greater number of users to interconnect, and to increase the coverage area. With a portal (i.e. Access Point), the wireless LAN can be easily connected into an existing wired LAN, allowing for easy expansion of the service. Compared to the PRISM II chip set, the PRISM 2.5 generation offers: • Low loss front end designed for maximum range • Higher level of chip integration and less peripheral components to reduce material costs • Support of optional IEEE 802.11 Short Preamble for significantly increased data throughput • Has a Type II PC Card form factor A complete Reference Design for the ISL37300P is available to ensure minimum time-to-market.

1 TM PRISM ® 2.5, 11Mbps Chip Set Overview USB Interface Intersil’s latest chip set, PRISM® 2.5, demonstrates the continuing progress Intersil is making toward more highly integrated, feature-rich WLAN silicon high performance solutions for future adapters smaller than present PCMCIA cards. Wireless LAN adapters in smaller forms (CompactFlash, MiniPCI, CardBus or embedded modules) are necessary for wide deployment of wireless connectivity in small devices such as laptops, palmtops, PDAs, and digital cameras, to name just a few. PRISM 2.5 makes a major step by integrating the Baseband Processor (BBP) and Medium Access Controller (MAC) - digital functions done by separate ICs in the PRISM II set. The PRISM 2.5 set also includes die shrinks of the power amplifier and RF/IF converter in much smaller form factors (micro-lead frame packages). • ISL3984 - 2.4GHz Power Amplifier and Detector • ISL3685 - 2.4GHz RF/IF Converter and Synthesizer • HFA3783 - I/Q Modulator/Demodulator Synthesizer • ISL3873 - Integrated MAC and Baseband Processor • ISL3183 - 748MHz VCO SPECIFICATIONS Variable Data Rates11, 5.5, 2 and 1Mbps Frequency Band2.4GHz ISM Band BER1x10 -5 at -83dBm Dual ModeIEEE802.11, 1 and 2Mbps 5.5 and 11Mbps Range100m Indoors (Note) Power ConsumptionSame as PRISM I, 2Mbps NOTE: Range test using AND-C-107 omnidirectional antenna.
