Design and implementation for 125 mW/MIPS ultra-high speed low power asymmetric digital subscriber line transceiver chip

Multimedia service with audio and video have become most desirable as the ADSL technology ideally converted from 1.5 Mbps full duplex HDSL technology via two twist-pair into 6.144 Mbps transmission technology via single twist-pair. This results in an interactive transmission service of T1 & E1 class data using the subscriber line without repeaters. The ADSL transceiver chipset is configured by DMT (Discrete Multi Tone modulation) scheme and RISC-based DSP core structure. Our ADSL chip is to be used in VOD, interactive interact service and/or teleconferencing system, etc. The operating frequency and dissipated power of the chip are 40 MHz and 5 W at 5 V.
