XRT83VSH28 - 8-CHANNEL E1 SHORT-HAUL LINE INTERFACE UNIT

Description

The XRT83VSH28 is a fully integrated 8-channel short-haul line interface unit (LIU) that operates from a 1.8V and a 3.3V power supply.

Using internal termination, the LIU provides one bill of materials to operate in E1 75Ω or 120Ω mode with minimum external components.

Features

  • are programmed through a standard parallel or serial microprocessor interface. 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.
