Overview
10BASE-T/100BASE-TX INTEGRATED PHYCEIVER WITH MII INTERFACE DATASHEET ICS1894-34 Description The ICS1894-34 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.
It is intended for MII Node applications and includes the Auto-MDIX feature that automatically corrects crossover errors in plant wiring.
The ICS1894-34 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.
The ICS1894-34 provides a Serial-Management Interface for exchanging command and status information with a Station-Management (STA) entity.
The ICS1894-34 Media-Dependent Interface (MDI) can be configured to provide half/full-duplex operation at data rates of 10 Mb/s or 100Mb/s.
In addition, the ICS1894-34 includes a programmable LED and interrupt output function.
The LED outputs can be configured through registers to indicate the occurance of certain events such as LINK, COLLISION, ACTIVITY, etc.
The purpose of the programmable interrupt output is to notify the PHY controller device immediately when a certain event happens instead of having the PHY controller continuously poll the PHY.
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.
The ICS1894-34 has deep power modes that can result in significant power savings when the link is broken.
Applications: NIC cards, PC motherboards, switches, routers, DSL and cable modems, game machines, printers, network connected appliances, and industrial equipment.
Features • Supports category 5 cables and above with attenuation in excess of 24dB at 100 MHz.
• Single-chip, ...
