SHDSL/ISDN DC Termination IC

Features

Description

• Meets wetting (sealing) current requirements per

ITU-T G.991.2

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.

• 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
