General Description
The KSZ8041NL is a single supply 10Base-T/100Base-TX Physical Layer Transceiver, which provides MII/RMII 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.
The KSZ8041NL represents a new level of features and performance and is an ideal choice of physical layer transceiver for 10Base-T/100Base-TX applications.
The KSZ8041RNL is an enhanced RMII version of the KSZ8041NL that does not require a 50MHz system clock.
It uses a 25MHz crystal for its input reference clock and outputs a 50MHz RMII reference clock to the MAC.

Features
• Single-chip 10Base-T/100Base-TX physical layer solution
• Fully compliant to IEEE 802.3u Standard
• Low power CMOS design, power consumption of <180mW
