1894KI-32LF General Description

The IDT1894-32 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 IDT1894-32 is intended for MII, Node applications that require the Auto-MDIX feature that automatically corrects crossover errors in plant wiring.The IDT1894-32 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 100MHz. With this IDT-patented technology, the IDT1894-32 can virtually eliminate errors from killer packets.The IDT1894-32 provides a Serial-Management Interface for exchanging command and status information with a Station-Management (STA) entity. The IDT1894-32 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.In addition, the IDT1894-32 includes a programmable interupt output function. This function consists of a digital output pin, an interrupt control register, a set of interrupt status register bits and a corresponding set of interrupt enable bits, and a pre-defined set of events which can be assigned as one of the interrupt sources. The purpose of this function is to notify the host of this PHY device when certain event happens via interrupt (the logic level on interrupt output pin going low or going high) instead of polling by the host. The events that could be used to generate interrupts are: receiver error, Jabber, page received, parallel detect fault, link partner acknowledge, link status change, auto-negotiation complete, remote fault, collision, etc.Applications: NIC cards, PC motherboards, switches, routers, DSL and cable modems, game machines, printers, network connected appliances, and industrial equipment.
