KSZ8001LI

The KSZ8001LI is a 10Base-T/100Base-TX/100Base-FX Physical -layer Transceiver, operating the core at 1.8V to meet low voltage and low power requirements. The solution provides MII/RMII/SMII interfaces to transmit and receive data. Unique mixed-signal design extends signalling 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.

• 1.8V CMOS design, power consumption 250mW
