CPC1465 SHDSL/ISDN DC Termination IC INTEGRATED CIRCUITS DIVISION Features Description Meets wetting (sealing) current requirements per The CPC1465 is a DC termination IC used in ITU-T G.991.2 Single-pair High-speed Digital Subscriber Line Integrated bridge rectifier for polarity correction (SHDSL) and Integrated Services Digital Network Uses inexpensive opto-coupler for DC signalling subscriber line (ISDN) equipment. It provides a Electronic inductor, breakover, and latch circuits polarity insensitive DSL loop sealing current DC Current limiting and excess power protection circuits termination with a recognizable device signature for ANSI SHDSL and ISDN compatible MLT systems. The CPC1465 passes low frequency MLT and SARTS compatible ISDN network signalling information via an Compatible with portable test sets inexpensive optocoupler to the NT1s internal control Excellent linearity logic. Compatible with GlobespanVirata and Conexant SHDSL transceiver chip set families Ordering Information Small SOIC or DFN Package Part Number Description DFN package 60 percent smaller than SOIC SOIC is pin compatible with Agere LH1465AAE DC Termination IC, 16-pin SOIC in tubes, CPC1465D 47/tube Applications DC Termination IC, 16-pin SOIC tape and reel, CPC1465DTR Router and bridge customer premises equipment 1000/reel Leased line equipment DC Termination IC, 16-pin DFN in tubes, CPC1465M T1/E1 network line cards and repeaters 52/tube Network Termination 1 (NT1) equipment DC Termination IC, 16-pin DFN tape and reel, CPC1465MTR Mechanized Loop Test (MLT) networks 1000/reel Switched Access Remote Test System (SARTS) networks Figure 1.
