1.2.9 LAN PHY_ICS1893
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 the
Auto-Negotiation features). When the ICS1893 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.
