ICS1893Y-10

Product Summary

The ICS1893Y-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 ICS1893Y-10 architecture is based on the ICS1892. The device supports managed or unmanaged node, repeater, and switch applications. The ICS1893Y-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 ICS1893Y-10 can virtually eliminate errors from killer packets.
