The enhanced Integrated Multiport Repeater (eIMR) device is a VLSI integrated circuit that provides a system-level solution to designing non-managed multiport repeaters. The eIMR device provides four Twisted Pair (TP) ports and one RAUI port for direct connection to MAC. The total number of ports per repeater unit can be increased by connecting multiple eIMR devices through their expansion ports, hence, minimizing the total cost per repeater port. The device is fabricated in CMOS technology and requires a single +5-V supply.
