DEMO KIT AVAILABLE  
DS21349  
3.3V T1/J1 Line Interface Unit  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
The DS21349 is a fully integrated LIU for long- Fully Integrated Line Interface Unit (LIU)  
haul or short-haul T1 applications over twisted- Pin Compatible with LevelOne LXT362  
pair installations. It interfaces to two twisted-pair Supports Both Long Haul and Short Haul  
lines—one pair for transmit and one pair for Crystal-Less Jitter Attenuator  
receive through an appropriate network Jitter Attenuator Programmable for Transmit  
interface. The device can be configured for  
or Receive Path  
control through software or hardware mode. Meets ANSI T1.102, T1.403, T1.408, and  
Software control is accomplished over a serial AT&T 62411  
port in hardware mode; individual pin settings Usable Receive Sensitivity of 0dB to -36dB  
allow stand-alone operation. The device provides  
a precise, crystal-less jitter attenuator that can be  
placed in either the transmit or receive path.  
That Allows the Device to Operate on  
0.63mm (22AWG) Cables Up to 6k Feet in  
Length  
Five Line Build-Out Settings for Short-Haul
