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.
