General

The ICS1893CF 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 ICS1893CF is intended for MII, Node applications that

require the Auto-MDIX feature that automatically corrects

crossover errors in plant wiring.

The ICS1893CF 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 ICS-patented

technology, the ICS1893CF can virtually eliminate errors from

killer packets.

The ICS1893CF provides a Serial-Management Interface for

exchanging command and status information with a

Station-Management (STA) entity. The ICS1893CF

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.

The ICS1893CF is available in a 300-mil 48-lead SSOP

package. The ICS1893CF shares the same proven

performance circuitry with the ICS1893BF and is a pin-for-pin

replacement of the 1893BF.

Applications: NIC cards, PC motherboards, switches,

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

network connected appliances, and industrial equipment.
