Clare is currently developing the CPC1465, a DC termination IC for SHDSL and ISDN/IDSL applications. The CPC1465 provides the DC termination functionality which is necessary to provide a path for the wetting current required by ITU-T G.991.2.
The device provides a polarity-insensitive DC termination for wetting current and a recognisable signature for MLT systems. It has superior linearity to minimise the harmonic distortion associated with its AC impedance and well- controlled turn-on and turn-off characteristics to minimise 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 300 V to handle power cross and lightning transients.
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.
The part will be manufactured in Clare's proven 320 V SOI process and packaged in a 16 pin SOIC.
