IRVINE, Calif.--(BUSINESS WIRE)--Jan. 28, 2002--Intersil Corporation (Nasdaq:ISIL):

• PRISM GT(TM) Chip Set Will Deliver Data Rates Up to 54 Mbps in the 2.4 GHz Band

• Performance Upgrade for 2.4 GHz WLANS and Backward Compatible With Existing Wi-Fi Systems

Intersil Corporation (Nasdaq:ISIL), the world's leading developer of silicon technology for Wireless Local Area Networks (WLANs), announced today the industry's first WLAN chip set designed to support the new 802.11g high-rate WLAN Draft Standard. Intersil's PRISM GT chip set will enable wireless networking systems to attain data transmission speeds up to 54 million bits per second (Mbps), while remaining backward compatible to the existing installed base of over 15 million Wi-Fi systems worldwide.

Intersil's newest WLAN solution will enable a next generation of high-data-rate platforms for operation in the 2.4 GHz band that deliver a five-fold speed increase. In addition, a 30 percent range advantage and lower power consumption are realized compared to systems operating in the 5 GHz spectrum. The chip set's cost and performance advantages will make it an ideal solution for high-bandwidth enterprise applications, such as wireless video conferencing and large file transfers, as well as advanced home networking applications such as multi-channel CD-quality audio and DVD-quality video streaming.

PRISM GT incorporates the 802.11g Draft Standard's mandatory modulation schemes - Complementary Code Keying (CCK), which is used in 802.11b, and Orthogonal Frequency Division Multiplexing (OFDM), used in 802.11a. "We firmly believe the mandatory modulations specified by the draft standard will meet all the needs of the market," said Larry Ciaccia, vice president and general manager of Intersil's Wireless Networking business. "Using CCK ensures backward-compatibility with the installed Wi-Fi base, while OFDM provides the speed required for today's high-bandwidth applications. The PRISM GT chip set is the world's first complete chip set designed for 802.11g and will catalyze the market for high speed wireless connectivity."

Intersil's first generation PRISM GT OEM Kit will begin sampling in the second quarter of this year with full production slated for the third quarter. The PRISM GT solution takes advantages from Intersil's industry-leading 802.11b chip sets, the direct down conversion architecture developed for PRISM(R) 3, and the digital signal processing expertise gained in the development of 5 GHz 802.11a products. The transceiver integrates the receiver, transmitter, synthesizer and filters onto a single chip, and interfaces directly with the Baseband Processor to provide system designers with a complete end-to-end WLAN chip set solution. The Medium Access Controller (MAC) includes enhanced security and network management features.

The PRISM GT transceiver is an RF-to-baseband solution that takes high frequency radio waves and directly converts them to baseband signals during reception, or directly up-converts them from the low-level baseband signal to radio frequency during transmission. This architecture completely eliminates the need for the intermediate frequency (IF) stage found in most radios. Eliminating the IF stage reduces complexity, bill-of-materials (BOM) and manufacturing costs, as well as enabling smaller form factors appropriate for portable, handheld devices.

Intersil's turnkey solutions approach will include mini-PCI and CardBus32-PC Card reference designs. Also offered will be all the development tools an original equipment manufacturer will need to quickly bring 802.11g WLAN products to market. The reference design kit includes the PRISM GT chip set, complete schematics, Gerber and layout files, BOM, manufacturing test utilities, PRISM lab test diagnostic tools, FAB drawings (PC board), antenna construction details, a technology license agreement, manufacturing, mechanical and assembly drawings.

The Global Wireless Market Embraces PRISM WLAN Technology

"Intersil is the number one manufacturer of wireless LAN chipsets and has been a driving force behind the success of WLANs," said a May 2001 WLAN report from Cahners In-Stat Group. Since introducing the PRISM WLAN chip set in 1996, industry-leading companies including Accton, Actiontec, Alcatel, ASUSTeK, Casio, Cisco, Compaq, 3Com, Dell, D-Link, GemTek, Hewlett Packard, IBM, Intel, Legend, Linksys, Nokia, Nortel, Panasonic, Quanta, Samsung, Sharp, Siemens, SOHOware, Sony, SpectraLink, Symbol, Z-Com and Zoom have incorporated PRISM chips in WLAN product designs. PRISM technology is designed to comply with the IEEE's 802.11 global standard, and Intersil is a founding sponsor of the Wireless Ethernet Compatibility Alliance (WECA), whose Wi-Fi brand is a mark of compatibility for 802.11-based systems.
