General Description
The KSZ8001 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/10BASE-
T/100BASE-FX applications.
