KSZ8563

The KSZ8563 is a highly-integrated, IEEE 802.3 compliant networking device that incorporates a layer-2+ managed Ethernet switch, two 10BASE-T/100BASE-TX physical layer transceivers (PHYs) and associated MAC units, and one MAC port with a configurable RGMII/MII/RMII interface for direct connection to a host processor/ controller, another Ethernet switch, or an Ethernet PHY transceiver.  KSZ8563 also implements IEEE 1588v2 Precision Timing Protocol one-step operation
