DP83959 8-Port Lite Ethernet Repeater Interface Controller

The DP83959 8-Port Lite Ethernet Repeater Interface Controller (LERIC8) is a single chip solution for unmanaged 10BASE-T Ethernet repeater (hub) products. By integrating electronics needed to support eight 10BASE-T ports, a full level/drive compatible AUI port for a backbone connection, and an internal power on reset circuit, a LERIC8 based design requires o.
