CPC1466

Broadband ADSL/VDSL DC Termination IC

Features

Description

• Meets wetting (sealing) current requirements per

ITU-T G.991.2

The CPC1466 is a DC Termination IC for broadband

ADSL/VDSL applications. The high-voltage,

monolithic device provides a path for DC wetting

(sealing) current in customer premises equipment

(CPE) to eliminate phone line corrosion on DSL

twisted-pair copper lines without telephone voice

services (i.e. only broadband services).

• Integrated bridge rectifier for polarity correction

• Uses inexpensive opto-coupler for DC sealing

current monitoring

• Electronic inductor, breakover, and latch circuits

• Current limiting and excess power protection circuits

• ADSL/VDSL compatible with low-pass filter network

• MLT and SARTS compatible

Internally, a bridge rectifier provides a

• Compatible with portable test sets

• Small SOIC or Micro-Leadframe Package (MLP)

• MLP package 60 percent smaller than SOIC

polarity-insensitive DC termination for DSL loop

sealing current. The IC includes an electronic inductor,

break-over and latch circuits, current limit and excess

power protection. A sealing current detect output

provides the means to monitor the loop for the

presence of sealing current in the loop.

Applications

• ADSL/VDSL broadband modems

• Router and bridge customer premises equipment

• Leased line equipment

• Mechanized Loop Test (MLT) networks

• Switched Access Remote Test System (SARTS)

networks

The CPC1466 is manufactured in Clare’s high voltage

BCDMOS process that is used extensively in

telephony applications worldwide.
