CPC1466 Broadband ADSL/VDSL DC Termination IC INTEGRATED CIRCUITS DIVISION Features Description Meets wetting (sealing) current requirements per The CPC1466 is a DC Termination IC for broadband ITU G.992.3 Annex 14.1 Region A ADSL/VDSL applications. The high-voltage, Integrated bridge rectifier for polarity correction monolithic device provides a termination for DC Uses inexpensive optocoupler for DC sealing current wetting (sealing) current in customer premises monitoring equipment (CPE) to eliminate phone line corrosion on Electronic inductor, breakover, and latch circuits DSL twisted-pair copper lines without telephone voice Current limiting and excess power protection circuits services (i.e. only broadband services). ADSL/VDSL compatible with low-pass filter network MLT and SARTS compatible Internally, a bridge rectifier provides a Compatible with portable test sets polarity-insensitive DC termination for DSL loop Small SOIC or DFN Package sealing current. The IC includes an electronic inductor, DFN package 60 percent smaller than SOIC 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 Applications presence of sealing current. ADSL/VDSL broadband modems Router and bridge customer premises equipment The CPC1466 is manufactured in IXYS Integrated Leased line equipment Circuits Divisions high voltage BCDMOS process that Mechanized Loop Test (MLT) networks is used extensively in telephony applications Switched Access Remote Test System (SARTS) worldwide. networks Figure 1.
