The Micrel KSZ8001S is a MII, RMII, SMII Ethernet PHY. The Micrel KSZ8001 family is a 10BASE-T/100BASE-TX/100BASE-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 KSZ8001 represents a new level of features and performance and is an ideal choice of physical layer transceiver for 100BASE-TX/10BASET/100BASE-FX applications.
