General Description

The ICS1890 is a fully integrated physical layer device supporting 10 and 100Mb/s CSMA/CD Ethernet applications. DTE (adapter cards or motherboards), switching hub, repeater and router applications are fully supported. The ICS1890 is compliant with the ISO/IEC 8802-3 Ethernet standard for 10 and 100Mb/s operation. A Media Independent Interface allowing direct chip-to-chip connection, motherboard-todaughterboard connection or connection via an AUI-like cable is provided. A station management interface is provided to enable command information and status information exchange. The ICS1890 interfaces directly to transmit and receive isolation transformers and can support shielded twisted pair (STP) and unshielded twisted pair (UTP) category 5 cables up to 105 meters. Operation in half duplex or full duplex modes at either 10 or 100 Mbps speeds is possible with control by Auto-Negotiation or manual selection. By employing Auto-Negotiation the technology capabilities of the remote link partner may be determined and operation automatically adjusted to the highest performance common operating mode.
