General Description

The KSZ8051 is an AEC-Q100 standard qualified single-supply 10BASE-T/100BASE-TX Ethernet physical-layer transceiver.

The KSZ8051 is a highly integrated PHY 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.
