3 Utopia Description
The new ADSL2+ standards will accelerate broad-
band applications beyond e-mail, web browsing
and data streaming. Internet Service Providers are
exploring several ways to increase their revenues
by offering new services and applications, and en-
larging their customer base. This can be accom-
plished using the increased quantity of new

features and annexes included in ADSL2+ prod-
ucts.
– Triple-play product offerings.
– On a 24+Mbps copper line link, several high-
definition video channels can be broadcasted
with new options offered to manage different la-
tency paths.
Increased subscribers base through extended
reach capabilities.
Reduced field deployment issues due to en-
hanced diagnostics capabilities and improved in-
teroperability.
Increased upstream speeds at lower costs for tele-
working and business symmetrical transmission
segments. By implementing bonding, both up-
stream and downstream bit-rates can be doubled
or further multiplied for high-end business applica-
tions.
The chipset allows OEM/ODM designers to ad-
dress the new services and applications needed
for the residential and SOHO markets up to the
large business segment. The chipset consists of a
new generation analog front-end chip (ST20184)
and digital chip (ST20196) integrating the DMT
modem and dedicated controller. When used to-
gether with an external network processor, a flexi-
ble and scalable platform can be developed to
handle the rapidly increasing bit rate demands and
the continuous introduction of additional multime-
dia functionalities and sophisticated networking
protocols.State-of-the-art ADSL2+ performance is

dition to the mandatory new features, the DMT engine includes some advanced techniques that differen-
tiate the product from its competitors; these include innovative Per Tone Equalizer (PTEQ) optimizing
short loop and bridge tap performances and reducing the impact of RFI in ADSL2+ mode. A high perfor-
mance echo canceller (EC) and a fully digital clock recovery scheme (TDI) further differentiate the
ST20190 ADSL2+ performances.
To be prepared for triple-play applications, a flexible TC-layer has been implemented. The cached ARM
micro-controller allows further improvement of the performances and allows fast and simple integration
with major third party network processors. Data is exchanged over the Utopia level 1 or 2 interface and
the commands via the ST Ctrl-E modem control command protocol.
■ Package : LBGA-208
■ Supply voltages: 3.3V and 1.2V
■ Temperature range: -40°C to 85°C
■ Typical power consumption: 700mW
5 Development support
ST Utopia chipsets are designed for OEM customers to minimize product development effort, to reduce
the implementation risks and to decrease time-to-market. Ease of integration has been implemented for
system designs. Including the use of standard Utopia and Ctrl-E interface for data and control, modem
software runs on the embedded controller separated from other system-related and application-specific
functions. The boundary between the two domains is provided by means of a simple modem control pro-
tocol (CTRL-E).
This “packaged modem” approach provides a self-contained ADSL modem solution, allowing system
manufacturers to concentrate on system issues.
Customers are supported through a complete kit which includes datasheets, application notes, schemat-
ics, bill of materials, layout information and modem software. In addition PC test and control software is
available to ease the evaluation and debugging phase.
