General
The ICS1892, an enhanced version of the ICS 1890, is a fully integrated, physical-layer device (PHY) that is compliant with both the 10Base-T and 100Base-TX CSMA/CD Ethernet Standard, ISO/IEC 8802-3. The ICS1892 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 cable with attenuation in excess of 24 dB at 100 MHz. With this ICS-patented technology, the ICS1892 can virtually eliminate errors from killer packets. The ICS1892 supports a broad range of applications: data terminal equipm ent (netwo rk in terf ace card s and motherboards), switches, repeaters, bridges, and routers. Its Media Independent Interface (MII) supports direct c h i p - t o - c h i p a n d m o t h e r b o a r d - t o - d a u g h t e r b o ar d connections as well as connections to an MII connector and cable. The ICS1892 also provides a Serial Management Interface for exchanging command and status information with a Station Management (STA) entity. The ICS1892 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 done manually (with input pins or control register settings) or automatically (using the Auto-Negotiation features). When the ICS1892 Auto-Negotiation sublayer is enabl...
