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.
