Abstract

This paper describes an SoC design for ADSL2/VDSL2 CPE residential gateways. The chip enables triple play: data, voice and video over DSL along with bridging/routing capabilities. This 90 nm CMOS technology chip integrates high speed data converters, DSL PHY, 4-VOIP channel voice subsystem, MIPS based broadband controller and a range of networking peripherals.
