The ST20190 is a new generation ADSL chipset from STMicroelectronics. It is highly integrated and has the flexibility to offer all standards, all annexes while being fully optimised for CPE applications. It provides all the required functions to implement a complete Utopia rate adaptive DMT ADSL modem. It consists of the optimised ADSL Analogue Front-End chip ST20184 and the digital chip ST20196 which includes a DMT/ATM modem, and a dedicated ADSL Transceiver Controller with associated Firmware. As shown in Fig.2, the chipset interfaces have been defined to allow direct integration into systems design, reducing both time-to-market and im-
