XRT7288

The XRT7288 is designed as one kind of CEPT1 line interface which is an integrated circuit that provides a 2.048 Mbits 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. This device performs receiver pulse regeneration, timing recovery, and transmit pulse driving functions. Also it 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.

Features of the XRT7288 are:(1)fully integrated 2.048 Mbits line interface;(2)intended for use in systems that must comply with CCITT specifications G.703, G.823, I.431, G.732, G.735 and G.739;(3)pin-selectable 75 or 120 operation;(4)monolithic clock recovery;(5)minimal external circuitry required;(6)robust frequency acquisition / phase-locked loop;(7)pin-selectable HDB3 encoder and decoder;(8)loopback modes for fault isolation;(9)multiple link-status and alarm features;(10)single-rail / dual-rail interface.
