KSZ8041TL/FTL/MLL
10Base-T/100Base-TX/100Base-FX
Physical Layer Transceiver
Data Sheet Rev. 1.2
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.
Micrel LinkMD® TDR-based cable diagnostics permit
identification of faulty copper cabling.
The KSZ8041TL represents a new level of features and
performance and is an ideal choice of physical layer
transceiver for 10Base-T/100Base-TX applications.
The KSZ8041FTL has all the identical rich features of the
KSZ8041TL plus 100Base-FX support for fiber and media
converter applications.
The KSZ8041MLL is the basic 10Base-T/100Base-TX
Physical Layer Transceiver version with MII support.
The KSZ8041TL and KSZ8041FTL are available in 48-pin,
lead-free TQFP packages. The KSZ8041MLL is provided
in the 48-pin, lead-free LQFP package (See Ordering
Information).
