Description
The CPC1466 is a DC Termination IC for broadband
ADSL/VDSL applications. The high-voltage,
monolithic device provides a termination 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.
The CPC1466 is manufactured in IXYS Integrated
Circuits Division’s high voltage BCDMOS process that
is used extensively in telephony applications
worldwide.
