General Description
The ICS1893BY-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 ICS1893BY-10 supports managed or unmanaged node, repeater, and switch applications.
The ICS1893BY-10 is intended for MII, Node applications that require the Auto-MIDIX feature that automatically corrects crossover errors in plant wiring.
The ICS1893BY-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 ICS1893BY-10 can virtually eliminate errors from killer packets.
The ICS1893BY-10 provides a Serial Management Interface for exchanging command and status information with a Station Management (STA) entity.
The ICS1893BY-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 automat i c a l l y (using the Auto-Negotiation features). When the ICS1893BY-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.
