10BASE-T/100BASE-TX INTEGRATED PHYCEIVER WITH RMII INTERFACE

ICS1894-40

Description

The ICS1894-40 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 RMII/MII, Node/Repeater

applications and includes the Auto-MDIX feature that

automatically corrects crossover errors in plant wiring.

The ICS1894-40 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 ICS1894-40 provides a Serial-Management Interface

for exchanging command and status information with a

Station-Management (STA) entity. The ICS1894-40

Media-Dependent Interface (MDI) can be configured to

provide either half-duplex or full-duplex operation at data

rates of 10 Mb/s or 100Mb/s.

In addition, the ICS1894-40 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 ICS1894-40 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.

•

– 10M or 100M full and half-duplex modes

– Loopback mode for Diagnostic Functions

•

Auto-MDI/MDIX crossover correction

Low-power CMOS (typically 300 mW)

Power-Down mode (typically 21mW)

Clock and crystal supported in MII mode

Programmable LEDs

Interrupt output pin

Fully integrated, DSP-based PMD includes:

– Adaptive equalization and baseline-wander

correction

– Transmit wave shaping and stream cipher

scrambler

– MLT-3 encoder and NRZ/NRZI encoder

•

Core power supply (3.3 V)

3.3 V/1.8 V VDDIO operation supported

Smart power control with deep power down feature

Available in 40-pin (6mm x 6mm) QFN package, Pb-free

Industrial Temp and Lead Free

Not recommended for new designs

— For full/half duplex RMII only interface support, please refer to ICS1894-43 datasheet.

— For full/half duplex MII only interface support, please refer to ICS1894-44 datasheet.

— ICS1894-43 and ICS1894-44 are pin-compatible with ICS1894-40.
