KSZ8041TL/FTL Product Brief Physical Layer Transceiver 10/100BASE-T/TX/FX transceiver applications. for 10Base-T/100Base-TX/100Base-FX The KSZ8041FTL has all the identical rich features of the KSZ8041TL plus 100Base-FX support for fiber and media converter applications. General Description The KSZ8041TL/FTL are single supply 10BaseT/100Base-TX Physical Layer Transceivers, which provide MII/RMII/SMII interfaces to transmit and receive data. These devices utilize 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 for identification of faulty copper cabling. Both KSZ8041TL and KSZ8041FTL are available in 48pin, lead-free TQFP packages.
