DEMO KIT AVAILABLE  
DS2149  
5V T1/J1 Line Interface Unit  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
The DS2149 is a fully integrated LIU for long-  
haul or short-haul T1 applications over twisted-  
pair installations. It interfaces to two twisted-pair  
lines—one pair for transmit and one pair for  
receive through an appropriate network  
interface. The device can be configured for  
control through software or hardware mode.  
Software control is accomplished over a serial  
port, in hardware mode; individual pin settings  
allow standalone operation. The device provides  
a precise, crystal-less jitter attenuator that can be  
placed in either the transmit or receive path.
