BEVERLY, Mass.--(BUSINESS WIRE)--Dec. 10, 2002

Clare, Inc., an IXYS company (Nasdaq:SYXI), today announced that it is currently developing the CPC1465, a DC termination IC for SHDSL and ISDN/IDSL applications. The CPC1465 provides the DC termination functionality that is necessary to provide a path for the wetting current required by ITU-T G.991.2.

The CPC1465 provides a polarity-insensitive DC termination for wetting current and a recognizable signature for MLT systems. The part has excellent linearity to minimize the harmonic distortion associated with its AC impedance and well-controlled turn-on and turn-off characteristics to minimize impulse noise and possible in-band signal energy into the DSL channel. Since it interfaces to the tip/ring pair, it is rated in excess of 300V to handle power cross and lightning transients. The part will be manufactured in Clare's proven 320V SOI process and packaged in a 16 pin SOIC. The CPC1465 is pin-compatible with the Agere LH1465AAE, the only other silicon solution available in the past.

Wetting current, also known as loop sealing current, is a low-level DC current (usually less than 20 mA) applied to a loop for the specific purpose of maintaining cable splice integrity by preventing the build-up of oxidation. The wetting current mainly addresses all-digital services on dry loops, unlike services with underlying POTS (ADSL for example) that inherently provide wetting current by means of off-hook loop current. With many service providers recently completing field trials for SHDSL, the symmetrical high-speed service with data rates up to 2.3 Mbps is poised for significant growth in 2003.

"Our proven high-voltage SOI process and telecommunications experience are a perfect match for the CPC1465," said John Battaglini, Marketing Director at Clare. "With Clare's long-term commitment to high-voltage processing and related applications, there are no longer any concerns about future supply of this critical IC product."

Design of the CPC1465 is now completed and the project is moving into the fab processing phase. First samples will be available in March, 2003. Full production release is targeted for 3Q-2003. Please contact your local sales representative for a copy of the existing preliminary datasheet.
