9 DESCRIPTION
The STLC60454 is a 4 channel ADSL AFE. It imple-
ments four analog transceiver functions required for
a central office modem. It connects the digital modem
chip with the line driver and hybrid balance circuit.
This 4 channel AFE has been designed with high dy-
namic range in order to greatly reduce the external fil-
ter requirements. Each single channel can be put in
power down mode and provides programmable filters
in the receive path. No external receiver is required.
