Broadband ADSL/VDSL DC Termination IC
Description
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).
Internally, a bridge rectifier provides a
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.
The CPC1466 is manufactured in Clare’s high voltage
BCDMOS process that is used extensively in
telephony applications worldwide.
