XRT83SL28 - 8-CHANNEL E1 SHORT-HAUL LINE INTERFACE UNIT
Exar (now MaxLinear)
Description
The XRT83SL28 is a fully integrated 8-channel E1 short-haul LIU which optimizes system cost and performance by offering key design
Features
The XRT83SL28 operates from a single 3.3V power supply. The LIU features are programmed through a standard serial microprocessor interface or hardware control. 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.
