Micrel Semiconductor KSZ8041NL
KSZ8041NL/RNL
10Base-T/100Base-TX
Physical Layer Transceiver
Revision 1.5
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 QFN packages (see Ordering Information).

Ordering Information
For the device marking (second column in the Ordering Information table), the fifth character of line 3 indicates whether
the device has gold wire bonding or silver wire bonding, as follows:
Gold wire bonding:
Silver wire bonding:
The letter “S” is not present as the fifth character of line 3.
The letter “S” is present as the fifth character of line 3.
For line three, the presence or non-presence of the letter “S” is preceded by YYWW, indicating the last two digits of the
year and the two digits work week for the chip date code, and is followed by xxx, indicating the chip revision and assembly
site.
