1 / 14 page  INTEGRATED CIRCUITS DIVISION DS-CPC1466-R03 www.ixysic.com 1 CPC1466 Broadband ADSL/VDSL DC Termination IC Features • Meets wetting (sealing) current requirements per ITU G.992.3 Annex 14.1 Region A • Integrated bridge rectifier for polarity correction • Uses inexpensive optocoupler 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 • Compatible with portable test sets • Small SOIC or DFN Package • DFN package 60 percent smaller than SOIC • Flammability rating UL 94 V-0 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 Figure 1. CPC1466 Block Diagram 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’ high voltage BCDMOS process that is used extensively in telephony applications worldwide.
