Brings telephony capability to broadband gateway products

IRVINE, Calif., October 18, 2000 — Intersil Corporation (NASDAQ: ISIL), a leading developer of silicon technology for wireless access and communications markets, today answered the call for products that provide reliable, toll grade voice-band telephony capability in residential and enterprise broadband gateway offerings.

Intersil’s latest gateway integrated circuit (IC) is specifically developed to facilitate Voice over Internet Protocol (VoIP) telephony in the next-generation of highly integrated cable modems, set top boxes, DSL modems and Broadband Wireless Access (BWA) subscriber terminals. The ISL5586 extends the versatility of the company’s existing gateway product family by adding devices that can also be incorporated into Data Over Cable Service Interface Specification (DOCSIS) compliant cable modem gateway products. Cable modems based on this standard will support voice-band telephony and high-speed data over the cable network infrastructure, offering the potential of low cost telephony in addition to Internet service, in-home networking and cable television for cable subscribers.

"Cable modem growth has been phenomenal this past year, " said Mike Althar, vice president for Intersil’s VoIP products. "The addition of Ethernet, HomePNA 2.0 and VoIP capability has driven the development of highly integrated circuit solutions that have been designed expressly for cable modems and other devices that converge voice and data streams. Combining a complex cable modem IC and tuner IC with four of Intersil’s new gateway ICs provides virtually all of the silicon content for a voice-enabled cable modem gateway, and greatly reduces the cost and time to market that is normally required for these complicated products. "

Intersil’s gateway ICs deliver "toll grade" telephony at low power consumption and comply with the stringent limitations imposed on broadband gateway products by service providers. "We are committed to a product roadmap that anticipates needs and delivers future solutions for these exciting communications applications, " said Althar.

Technical Information
The ISL5586 meets the telephony requirements for Voice over DSL (VoDSL) integrated access devices (IAD) or voice enabled DSL modems and BWA subscriber terminals, and is compatible with a variety of analog subscriber equipment such as V.90 modems and fax machines. Toll quality voice signals are transmitted to an integrated cable modem chip or to a voice-band codec over a low level, low noise differential signal interface. Intersil’s ISL5586 delivers controlled power to the telephone handset while consuming only 57mW in additional overhead power. The integrated ringing function eliminates the need for costly ring generators and electromechanical relays.
