The ICS1894-40 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, ISO/IEC 8802.3. It is intended for RMII/MII, Node/Repeater applications and includes the Auto-MDIX feature that automatically corrects crossover errors in plant wiring.
The ICS1894-40 incorporates Digital-Signal Processing (DSP) control in its Physical-Medium Dependent (PMD) sub-layer. 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 100MHz. The ICS1894-40 provides a Serial-Management Interface for exchanging command and status information with a Station-Management (STA) entity. The ICS1894-40 Media-Dependent Interface (MDI) can be configured to provide either half-duplex or full-duplex operation at data rates of 10 Mb/s or 100Mb/s.
