8-port Lite Ethernet Repeater Interface Controller - National Semiconductor

The DP83959 8-Port Lite Ethernet Repeater Interface Controller (LERIC8) is a single chip solution for unman- aged 10BASE-T Ethernet repeater (hub) products. By inte- grating 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 only the addition of a few passive components: crystal, transformers, connectors and a power source. The LERIC8 provides on-chip LED Drivers that connect di- rectly to LEDs via series resistors. In addition to the Link OK, Port Partition, Global Activity and Global Collision LED outputs, the LERIC8 provides an on chip network trafc level monitor circuit with 8 LED outputs to drive a bargraph type Display The LERIC8 also provides an LED and Inter Repeater Bus Interface that is compatible with the DP83955/6 LERIC products.
