FREMONT, Calif. -- June 1, 1998 --Demonstrating its ongoing commitment to provide universal communications solutions to its modem customers, Cirrus Logic Inc. (NASDAQ:CRUS) today announced the shipment of its V.90 code to channel partners. Extensively tested with the V.90 Work Group plus other well known server modem developers, Cirrus Logic's 56K modem code is one of the first to include Dual Recognition Mode, a feature that automatically selects between the existing x2 modem technologies and V.90 depending on the server's modem type. Now modems based on Cirrus Logic's 56K CrystalClear(TM) modem chips can provide a reliable connection with any Internet Service Provider that supports the emerging V.90 56K standard.

While the explosive growth in Internet usage has driven consumer demand for high speed access, the migration to faster 56K modems has been slowed by the lack of a consistent transmission standard among modem developers and ISPs. Cirrus Logic's V.90 code smooths the transition to the emerging 56K standard, enabling customers to continue to communicate with their current ISP whether the provider uses V.90 or the earlier x2 technology.

"During the transition to V.90, we will continue to support modem manufacturers to ensure a seamless migration to the new standard," confirmed Karl Nordling, vice president of modem engineering for Cirrus Logic. "Moreover, with automatic selection of V.90 or x2 transmission modes, users of V.90 modems with our chip solution don't need to be concerned about the V.90 upgrade status of their Internet Service Provider."

Support for the V.90 56K standard applies to any modems based on Cirrus Logic's MD56xx modem chip sets. Customers who currently own software-upgradable 56K modems based on Cirrus Logic's FastPath technology have the opportunity to upgrade by contacting their modem manufacturer. Customers buying a new V.90 modem based on Cirrus Logic's FastPath technology will benefit from superior line performance as soon as their ISP offers V.90 service. "This will certainly proliferate the usage of 56K modems," Nordling added. "But more importantly, for users of modems with our chip solution, it will enhance their experience in accessing the Internet by increasing both flexibility and performance."

* 56Kbps technology refers to server download speeds only and requires compatible modems at server sites. V.90 products are capable of 56Kbps downloads; however, due to FCC rules which restrict power output of service providers' modems, current download speeds are limited to 53 Kbps. Actual speeds may vary depending on line conditions and other factors. Uploads travel at speeds up to 31.2 Kbps. Requires analog phone line compatible with 56K technology.
