DESCRIPTION  
Burr-Brown’s Analog Front End chip greatly reduces  
the size and cost of an xDSL (Digital Subscriber Line)  
system by providing all of the active analog circuitry  
needed to connect a digital signal processor to an  
external compromise hybrid and line transformer. The  
AFE1144 is optimized for HDSL (High bit rate DSL)  
and for lower speed MDSL (Medium speed DSL) and  
RADSL (Rate Adaptive DSL) applications. Because  
the transmit and receive filter responses automatically  
change with clock frequency, the AFE1144 is particu-  
larly suitable for RADSL and multiple rate DSL sys-  
tems. The device operates over a wide range of data  
rates from 64kbps to 1168kbps.  
Functionally, this unit consists of a transmit and a  
receive section. The transmit section generates analog  
signals from 2-bit digital symbol data and filters the  
analog signals to create 2B1Q symbols. The on board  
differential line driver provides a 13.5dBm signal to  
the telephone line. The receive section filters and  
digitizes the symbol data received on the telephone  
line. This IC operates on a single 5V supply. The  
digital circuitry in the unit can be connected to a  
supply from 3.3V to 5V. It is housed in a SSOP-28  
package.
