Abstract :
From Time domain to Atm domain, the complete digital signal processing required by ADSL technology has been integrated onto a single device called SACHEM. High programmability along with flexible architecture enable the device to serve for both network and line termination. Mapping on a 0.35 μm standard digital CMOS technology makes SACHEM a cost effective solution as well as a low power device, consuming only 800 mW at 3.3 V
