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

ICS1894-40

Description

Features

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.

• Supports category 5 cables with attenuation in excess of

24dB at 100 MHz.

• Single-chip, fully integrated PHY provides PCS, PMA,

PMD, and AUTONEG sub layers functions of IEEE

standard.

The ICS1894-40 is intended for MII, Node applications that

require the Auto-MDIX feature that automatically corrects

crossover errors in plant wiring.

• 10Base-T and 100Base-TX IEEE 8802.3 compliant

• MIIM (MDC/MDIO) management bus for PHY register

configuration

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. With this

IDT-patented technology, the ICS1894-40 can virtually

eliminate errors from killer packets.

• RMII interface support with external 50 MHz system clock

• Single 3.3V power supply

• Highly configurable, supports:

– Media Independent Interface (MII)

– Auto-Negotiation with Parallel detection

– Node applications, managed or unmanaged

– 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

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- or full-duplex operation at data rates of

10 Mb/s or 100Mb/s.

In addition, the ICS1894-40 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

• Interrupt pin option

• 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

• Single power supply (3.3 V)

• Built-in 1.8 V regulator for core

• Available in 40-pin (5mm x 5mm) QFN package, Pb-free

• Available in Industrial Temp and Lead Free

Applications: NIC cards, PC motherboards, switches,

routers, DSL and cable modems, game machines, printers,

network connected appliances, and industrial equipment.
