Description

3.3V 10BASE-T/100BAS
The 1893YI-10LF is a low-power, physical-layer device (PHY) that supports the ISO/IEC 10Base-T and 100Base-TX Carrier-Sense Multiple Access/Col lision Detection (CSMA/CD) Ethernet standards. The 1893YI-10LF architecture is based on the ICS1892. The 1893YI-10LF supports managed or unmanaged node, repeater, and switch applications.

The 1893YI-10LF 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 1893YI-10LF can virtually eliminate errors from killer packets.

The 1893YI-10LF provides a Serial Management Interface for exchanging command and status information with a Station Management (STA) entity.

The 1893YI-10LF 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 1893YI-10LF 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.
