DC-termination ICs tailored for ADSL/VDSL applications

Beverly, Mass.—Clare Inc., a wholly owned subsidiary of IXYS Corp., 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's linearity is 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 is has a maximum rating of 300V to handle power cross and lightning transients.

The ICs are manufactured on Clare's 320V Silicon-On-Insulator (SOI) process and packaged in a 16 pin SOIC or MLP. By Ismini Scouras
