CPC1466 Broadband
ADSL / VDSL DC Termination IC
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
Features
• Meets wetting (sealing) current requirements per
• Integrated bridge rectifier for polarity correction
• Uses inexpensive opto-coupler for DC sealilng current
• 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
• Compatible with portable test sets
• Small SOIC or DFN Package
• DFN package 60 percent smaller than SOIC

electronic inductor, breakover 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.
