The ST20190 is a new generation ADSL chipset
from STMicroelectronics. It is highly integrated
and has the flexibility to offer all standards, all an-
nexes while being fully optimised for CPE applica-
tions. 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 mo-
dem, and a dedicated ADSL Transceiver Control-
ler with associated Firmware.
As shown in Fig.2, the chipset interfaces have
been defined to allow direct integration into sys-
tems design, reducing both time-to-market and im-
