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 is 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 MLP.
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, 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.
