DESCRIPTION  
Burr-Brown’s Analog Front End minimizes the size  
and cost of a single pair High bit rate Digital Sub-  
scriber Line (HDSL) system by providing all of the  
active analog circuitry needed to connect an HDSL  
digital signal processor to an external compromise  
hybrid and an HDSL line transformer. The transmit  
and receive filter responses automatically change with  
clock frequency, allowing the AFE1224 to operate  
over a wide range of data rates. The power dissipation  
of the device can be reduced under digital control for  
operation at lower speeds. The AFE1224 will operate  
at bit rates from 64kbps to 2.320Mbps.  
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. The AFE1224 operates on a single 5V supply.  
The digital circuitry in the unit can be connected to a  
supply from 3.3V to 5V. The chip uses only 355mW  
for full-speed operation. It is housed in a 28-lead  
SSOP package.
