GENERAL DESCRIPTION  
The XR-T7288 CEPT1 Line Interface is an integrated  
circuit that provides a 2.048 Mbits/s line interface to either  
twisted-pair or coaxial cable as specified in CCITT  
requirements G.703, G.823, I.431, G.732, and G.735  
G.739. The device performs receive pulse regeneration,  
timing recovery, and transmit pulse driving functions. The  
XR-T7288 device is manufactured by using low-power  
CMOS technology and is available in a 28-pin, plastic DIP  
or in a 28-pin, plastic SOJ package for surface mounting.  
The XR-T7288 device is functionally compatible with the  
LC1135B device. The digital circuitry is shown in  
Figure 1.; the analog circuitry is shown in Figure 6.
