www.DataSheet4U.com MAY 2006 XRT83SH38 8-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT REV. 1.0.3 GENERAL DESCRIPTION The XRT83SH38 is a fully integrated 8-channel shorthaul line interface unit (LIU) that operates from a single 3.3V power supply. Using internal termination, the LIU provides one bill of materials to operate in T1, E1, or J1 mode with minimum external components. The LIU features are programmed through a standard microprocessor interface, serial interface or controlled through.

8-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT

www.DataSheet4U.com MAY 2006 XRT83SH38 8-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT REV. 1.0.3 GENERAL DESCRIPTION The XRT83SH38 is a fully integrated 8-channel shorthaul line interface unit (LIU) that operates from a single 3.3V power supply. Using internal termination, the LIU provides one bill of materials to operate in T1, E1, or J1 mode with minimum external components. The LIU features are programmed through a standard microprocessor interface, serial interface or controlled through Hardware mode. EXAR’s LIU has patented high impedance circuits that allow the transmitter outputs and receiver inputs to be high impedance when experiencing a power failure or when the LIU is powered off. Key design features within the LIU optimize 1:1 or 1+1 redundancy and non-intrusive monitoring applications to ensure reliability without using relays. The on-chip clock synthesizer generates T1/E1/J1 clock rates from a selectable external clock frequency and outputs a clock reference of the line rate chosen. Additional features include RLOS, a 16-bit LCV counter for each channel, AIS, QRSS generation/ detection, TAOS, DMO, and diagnostic loopback modes. APPLICATIONS • T1 Digital Cross-Connects (DSX-1) • ISDN Primary Rate Interface • CSU/DSU E1/T1/J1 Interface • T1/E1/J1 LAN/WAN Routers • Public switching Systems and PBX Interfaces • T1/E1/J1 Multiplexer and Channel Banks FIGURE 1.
