Microchip Technology KSZ8041 Ethernet Transceivers

Microchip Technology KSZ8041 Ethernet Transceivers are single-supply 10BASE-T/100BASE-TX physical layer transceivers that provide MII/RMII/SMII interfaces to transmit and receive data. These transceivers utilize a unique mixed-signal design to extend signaling distance while reducing power consumption. The KSZ8041 transceivers feature HP auto MDI/MDI-X, which provides the most robust solution for eliminating the need to differentiate between crossover and straight-through cables. The LinkMD® TDR-based cables diagnostic permits the identification of faulty copper cabling.

The KSZ8041RNL transceivers are an enhanced RMII version of the KSZ8041NL that does not require a 50MHz system clock. These transceivers use a 25MHz crystal for its input reference clock and output a 50MHz RMII reference clock to the MAC. The KSZ8041NL and KSZ8041RNL transceivers are available in 32-pin and lead-free QFN packages. The KSZ8041TL and KSZ8041FTL transceivers are available in a 48-pin, lead-free TQFP package. The KSZ8041MLL transceivers are provided in the 48-pin and lead-free LQFP package. Typical applications include printers, game consoles, IPTVs, IP phones, IP Set-top boxes, and media converters.
