General Description

The KS8001 is a 10BASE-T/100BASE-TX/FX Physical Layer Transceiver, operating the core at 1.8 volts to meet low voltage and low power requirements. The solution provides MII/RMII/SMII interfaces to transmit and receive data. A unique mixed-signal design extends signaling distance while reducing power consumption.

HP Auto MDI/MDI-X provides the most robust solution for eliminating the need to differentiate between crossover and straight-through cables.

Featuring LinkMD cable diagnostics, which allows detection of common cabling plant problems such as open and short circuits, the KS8001 represents a new level of features and performance and is an ideal choice of physical layer transceiver for 100BASE-TX/10BASE T/100BASE-FX applications.
