KSZ8041NL/RNL
10Base-T/100Base-TX
Physical Layer Transceiver
Data Sheet Rev. 1.4
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.
The KSZ8041NL and KSZ8041RNL are available in 32-
pin, lead-free MLF® (QFN per JDEC) packages (See
Ordering Information).
