7 DEVELOPMENT SUPPORT FOR THE ST20190

Great care has been taken in defining the ST20190 to ease its integration into system designs. In partic-

ular, this is achieved:

– At hardware level: by using one standard interface (ATM Utopia) both for data transfer and for control

– At firmware level: by clearly separating the modem firmware, run on the embedded Transceiver Con-

troller from other systems related and application-specific functions.

The boundary between the two domains is provided by means of a simple modem control protocol (CTRL-

E). This "packaged modem" approach provides a self-contained ADSL modem solution, allowing system

manufacturers to concentrate on system issues. The ST20190 comes in a package with full firmware,

schematics, Bill of Materials and layout information for the ADSL modem part. It is further supported by a

full development environment comprising:

– Evaluation boards

– PC firmware driver for CTRLE

– DeTONEator S/W for CTRLE to a PC

– ADSL test and control FW running on PC
