1 / 15 page  DS-CPC1465 - R02 www.clare.com 1 CPC1465 SHDSL/ISDN DC Termination IC Features • Meets wetting (sealing) current requirements per ITU-T G.991.2 • Integrated bridge rectifier for polarity correction • Uses inexpensive opto-coupler for DC signalling • Electronic inductor, breakover, and latch circuits • Current limiting and excess power protection circuits • ANSI SHDSL and ISDN compatible • MLT and SARTS compatible • Compatible with portable test sets • Excellent linearity • Compatible with GlobespanVirata and Conexant SHDSL transceiver chip set families • Small SOIC or DFN Package • DFN package 60 percent smaller than SOIC • SOIC is pin compatible with Agere LH1465AAE Applications • Router and bridge customer premises equipment • Leased line equipment • T1/E1 network line cards and repeaters • Network Termination 1 (NT1) equipment • Mechanized Loop Test (MLT) networks • Switched Access Remote Test System (SARTS) networks Description The CPC1465 is a DC termination IC used in Single-pair High-speed Digital Subscriber Line (SHDSL) and Integrated Services Digital Network subscriber line (ISDN) equipment. It provides a polarity insensitive DSL loop sealing current DC termination with a recognizable device signature for MLT systems. The CPC1465 passes low frequency ISDN network signalling information via an inexpensive optocoupler to the NT1’s internal control logic. Ordering Information Figure 1.
