Systems, Inc.
ICS1890
10Base-T/100Base-TX Integrated PHYceiver聶
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-to-
daughterboard 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.
