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
