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.
