Overview

The IDT1893Y-10 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 IDT1893Y-10 architecture is based on the IDT1892. The IDT1893Y-10 supports managed or unmanaged node, repeater, and switch applications. The IDT1893Y-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 IDT-patented technology, the IDT1893Y-10 can virtually eliminate errors from killer packets. The IDT1893Y-10 provides a Serial Management Interface for exchanging command and status information with a Station Management (STA) entity. The IDT1893Y-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 IDT1893Y-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.
