General
The ICS1893 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 ICS1893 architecture
is based on the ICS1892. The ICS1893 supports managed
or unmanaged node, repeater, and switch applications.
The ICS1893 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
ICS1893 can virtually eliminate errors from killer packets.
The ICS1893 provides a Serial Management Interface for
exchanging command and status information with a Station
Management (STA) entity.
The ICS1893 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 th e
Auto-Negotiation features). When the ICS189 3
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.
