General Description
The KSZ8041TL is a single supply 10Base-T/100Base-TX
Physical Layer Transceiver, which provides MII/RMII/SMII
interfaces to transmit and receive data. It utilizes a unique
mixed-signal design to extend 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.
