Intersil’s New PRISM® II Baseband Processor in Full Production
Baseband Processor HFA3863 joins the elite PRISM II portfolio
IRVINE, CA, September 18, 2000 — Intersil Corporation (NASDAQ: ISIL), the world’s leading developer of silicon technology for Wireless Local Area Networks (WLANs), announced today that its new Baseband Processor (BBP), the HFA3863 is now in full production. The HFA3863 joins Intersil’s award-winning PRISM II WLAN portfolio, still the world’s only complete solution for next generation wireless networking products.
This new digital silicon "engine" for wireless networking systems sets a new benchmark for such devices by providing best-in-class performance for multipath tolerance. The HFA3863 BBP is the most advanced addition to Intersil’s extensive portfolio of PRISM baseband chips for IEEE 802.11-based wireless networking systems. PRISM chips are used in WLAN systems from industry-leading computer, communications and networking companies.
Specifically designed for WLAN systems requiring robust operation in dense office environments and factory floors, the new BBP supports areas where severe multipath interference is a significant threat to signal integrity and throughput. The new chip’s delay spread tolerance of >300 nanoseconds helps combat these problems.
"Our customers asked for extended range and data throughput and Intersil responded to their needs. Our new HFA3863 BBP provides the best delay spread performance available, " said Larry Ciaccia, vice president and general manager of Intersil’s PRISM Wireless Products business. "This new breakthrough is vitally important for business and home users who need to maximize reliable throughput to support data, Voice over Internet Protocol (VoIP) and multimedia applications. "
Technical Features
The HFA3863 delivers superior multipath performance versus existing designs through the addition of an equalizer, which helps ensure radio signal integrity by substantially reducing inter-symbol and inter-chip interference. The device’s on-board RAKE receiver complements the equalization function, resulting in an industry-leading delay spread tolerance of greater than 300 nanoseconds at 11 megabits-per-second (Mbps), based on two-ray measurements. Collectively, these features help PRISM-enabled WLAN devices achieve robust throughput and extended operating range.
The HFA3863 BBP, with associated firmware upgrade for the MAC, is a drop-in replacement to the HFA3861B baseband processor. The new chip delivers an 11 Mbps data rate through use of Complementary Code Keying (CCK) technology, the modulation technique utilized in the IEEE 802.11b high rate standard for wireless LANs. Its variable data rate allows operation at 1, 2, 5.5 or 11Mbps. This variable rate allows 11 Mbps systems to downshift when conditions deteriorate, ensuring link integrity. It also makes such systems backwards compatible with older WLAN equipment operating at the 1 and 2 Mbps data rate.
Automatic Gain Control (AGC) is provided for during both transmit and receive to obtain maximum performance in the analog portions of the transceiver. Built-in flexibility allows the HFA3863 to be configured through a general-purpose control bus to fit a broad range of wireless applications including IEEE 802.11 WLANs, PCMCIA wireless transceivers, RF modems, TDMA packet protocol radios, wireless bridges and a variety of portable RF-based devices.
Packaging, Availability and Pricing
Housed in a plastic Thin Quad Flat Package (TQFP) suitable for PCMCIA board applications, the HFA3863 is available now, priced at $16.20 in 10K quantities. An evaluation board (HFA3863-EVAL1) and complete data sheet are also available. For more information, visit Intersil’s homepage at www.intersil.com/prism.
Adoption of PRISM WLAN Technology
Since introducing the PRISM WLAN chip set in 1996, over fifty companies have incorporated PRISM chips in more than 100 product designs. In a May 2000 report, the Cahners In-Stat Group called Intersil "the dominant force in the WLAN chip set marketplace with their PRISM chipsets holding the majority of market share. " PRISM technology is designed to comply with the IEEE’s 802.11b 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 802.11b-based systems. PRISM chips are used in WLAN systems from industry-leading companies including Alcatel, Cisco, Nokia, Siemens, Compaq, 3Com, Dell, Nortel, Samsung, SpectraLink, Symbol Technologies and Zoom.
