General Description
●The KSZ8051 is a single supply 10Base-T/100Base-TX Ethernet physical layer transceiver for transmission and reception of data over standard CAT-5 unshielded twisted pair (UTP) cable.
●The KSZ8051 is a highly integrated, compact solution. It reduces board cost and simplifies board layout by using on-chip termination resistors for the differential pairs and by integrating a low noise regulator to supply the 1.2V core.
●The KSZ8051MNL offers the Media Independent Interface (MII) and the KSZ8051RNL offers the Reduced Media Independent Interface (RMII) for direct connection with MII/RMII compliant Ethernet MAC processors and switches.
