Document Stage: Preliminary Release
3.3-V 10Base-T/100Base-TX Integrated PHYceiver
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.
www.DataSheeTt4hUe.cIoCmS1893CY-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
register settings) or automatically (using the
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.
Features
