General

The ICS1893CY-10 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. The ICS1893CY-10

supports managed or unmanaged node, repeater, and

switch applications.

The ICS1893CY-10 is intended for MII, Node applications

that require the Auto-MIDIX feature that automatically

corrects crossover errors in plant wiring.

The ICS1893CY-10 incorporates digital signal processing

(DSP) in its Physical Medium Dependent (PMD) sublayer.

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 ICS-patented

technology, the ICS1893CY-10 can virtually eliminate errors

from killer packets.

The ICS1893CY-10 provides a Serial Management Interface

for exchanging command and status information with a

Station Management (STA) entity.

The ICS1893CY-10 Media Dependent Interface (MDI) can

be configured to provide either half- or full-duplex operation

at data rates of 10 MHz or 100 MHz. The MDI configuration

can be established manually (with input pins or control

r e g i s t e r s e t t i n g s ) o r a u t o m a t i c a l l y ( u s i n g t h e

Auto-Negotiation features). When the ICS1893CY-10

Auto-Negotiation sublayer is enabled, it exchanges

technology capability data with its remote link partner and

automatically selects the highest-performance operating

mode they have in common.
