Clare Introduces Next Addition to Growing Family of DC-Termination ICs for ADSL/VDSL Applications

The CPC1466 is used in ADSL/VDSL Customer Premises Equipment (CPE) to terminate the DC current of DSL twisted-pair copper lines without telephone voice services

January 8, 2008–Beverly, Massachusetts, USA – Clare, Inc., an IXYS company (NASDAQ: IXYS – News), today announced that it is in full production with the CPC1466 DC-termination IC for ADSL and VDSL CPE applications such as broadband modems and leased-line equipment. The CPC1466 has the DC termination functionality necessary to complete the path for wetting current specified by ITU-T G.992.3. The IC also includes an integrated current limit feature and detect output that indicates wetting current is being applied.

The CPC1466 provides a polarity-insensitive DC termination for wetting current and a recognizable signature for MLT and SARTS systems. The part has excellent linearity, 70dB typical, to minimize harmonic distortion associated with its AC impedance and has well-controlled turn-on and turn-off characteristics to minimize impulse noise and generation of in-band signal energy into the DSL channel. Since it interfaces with the tip/ring pair, it has a maximum rating of 300V to handle power cross and lightning transients. These ICs are manufactured on Clare's proven 320V Silicon-On-Insulator (SOI) process and packaged in a 16-pin SOIC or DFN.

Wetting current, also known as loop sealing current, is a low-level DC current (usually less than 20mA) 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, unlike services with underlying POTS (Plain Old Telephone Service) that inherently provide loop current while off-hook. In addition, service providers have the option of providing ADSL2+ broadband services to customers without POTS and meet the requirement for wetting current. With many service providers implementing ADSL2+ and VDSL, service growth in the symmetrical high-speed market is up 50% since 2003.

Pricing and Availability
Design of the CPC1466D and CPC1466M, 16-pin SOIC and micro-lead chip, is now complete and in full production. Pricing of the CPC1466 in 10K volumes is $1.62. Contact a local sales representative through the link near the bottom of this announcement.
