描述 Description

The KSZ9563 is a highly-integrated, IEEE 802.3 compliant networking device that incorporates a layer-2+ managedGigabit Ethernet switch, two 10BASE-T/100BASE-TX/1000BASE-T physical layer transceivers (PHYs) and associatedMAC 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.? KSZ9563 also implements IEEE 1588v2 Precision Timing Protocol.

Full register access is available by SPI or I2C interfaces,and by optional in-band management via any of the data ports.PHY register access is provided by a MIIM interface.

Security features include support for IEEE 802.1X port-based authentication and Access Control List (ACL) filtering.

An assortment of power-management features includingEnergy-Efficient Ethernet (EEE) have been designed in tosatisfy energy efficient environments.
