1893CFLFT General Description

The IDT1893C is a low-power, physical-layer device (PHY) that supports the ISO/IEC 10Base-T and 100Base-TX Carrier-Sense Multiple Access/Collision Detection (CSMA/CD) Ethernet standards, ISO/IEC 8802-3. The IDT1893C is intended for MII, Node applications that require the Auto-MDIX feature that automatically corrects crossover errors in plant wiring. The IDT1893C incorporates Digital-Signal Processing (DSP) control in its Physical-Medium Dependent (PMD) sub layer. As a result, it can transmit and receive data on unshielded twisted-pair (UTP) category 5 cables with attenuation in excess of 24 dB at 100 MHz. With this IDT-patented technology, the IDT1893CF can virtually eliminate errors from killer packets. The IDT1893C provides a Serial-Management Interface for exchanging command and status information with a Station-Management (STA) entity. The IDT1893C Media-Dependent Interface (MDI) can be configured to provide either half- or full duplex operation at data rates of 10 Mb/s or 100Mb/s. The IDT1893C shares the same proven performance circuitry with the IDT1893BF and is a pin-for-pin replacement of the 1893BF. Applications: NIC cards, PC motherboards, switches, routers, DSL and cable modems, game machines, printers, network connected appliances, and industrial equipment.
