The KSZ8041 is a single supply 10Base-T/100Base-TX Physical Layer Transceiver, which provides MII/RMII/SMII 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 KSZ8041 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. 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.
