Clare Expands Telecommunication LCAS Product Family Using Advanced SOI IC Technology, for Voice and Integrated Voice and Data Applications.

Business Editors/High-Tech Writers

BEVERLY, Mass.--(BUSINESS WIRE)--June 5, 2003

Clare, Inc., an IXYS company (NASDAQ: SYXI), today announced the availability of two new members of its Line Card Access Switch (LCAS) product family. The CPC7584 and a new package option for the CPC7583 provide designers with maximum flexibility in line card design for both traditional voice and integrated voice-data (IVD) line cards found in central office (CO) and digital loop carrier (DLC) communications equipment.

The CPC7584 is a monolithic solid-state switch that replaces the functionality of two 2-Form-C electromechanical relays (EMR). It contains switches for tip and ring line break, ringing injection/return and channel test/test-in access. The CPC7584 is aimed at systems where the majority of traditional LCAS functionality and benefits are required but a separate drop test method is used because of high-frequency loop testing or abnormally high drop test voltages are required.

There are 3 electrical versions of the CPC7584 that are differentiated by their internal protection functionality and logic states. The "C" version (CPC7584xC) has the maximum functionality as it contains an internal SCR for tertiary line card protection as well as a unique channel test monitor state. The monitor state allows for simultaneous closure of the break and channel test switch pairs so nonintrusive service monitoring of the line can be performed. All versions of the CPC7584 are available in both a 16 pin SOIC and a leadless, chip-scale 16 pin Micro-Leadframe Package (MLP).

The 20 pin CPC7583Zx offers an alternative package option for existing silicon that has already been shipping in high-volume production in the 28 pin SOIC and 28 pin MLP packages. The new 20 pin SOIC package represents a 30% area reduction compared to the 28 pin SOIC and an alternative option for customers not yet ready to make the jump to the chip-scale MLP version.

"As line card design requirements evolve, the rollout of new LCAS products is critical," said John Battaglini, Marketing Director at Clare. "Having a qualified, proven SOI process and wafer fab in-house gives Clare a unique competitive advantage that allows us to respond quickly to rapidly changing customer requirements."

Pricing and Availability

Samples of the CPC7584BC are available now with production planned for 3Q-2003. CPC7583ZA samples and production quantities are both available now. Please contact your local sales rep for pricing and leadtime information.
