1.0 Introduction
The KSZ8795 family is Micrel Operations new generation integrated 5-port switch with Gigabit
up-link. The KSZ8795CLX is one of KSZ8795 family. KSZ8795CLX contains four MAC/PHYs
for four copper ports and one GMAC5 interface with configurable GMII/RGMII/MII/RMII
interfaces. The device had been designed with cost sensitive systems in mind but still offers a
multitude of new features such as port based security ACL filtering, 802.1az EEE, LinkMD and so
on. Also support port and tag based VLAN; QoS priority; SPI and MDC/MDIO interfaces for the
registers access. The KSZ8795 family is an excellent choice in broadband gateway applications,
integrated broadband router applications, industrial automatic, automotive, etc. fields and as a
standalone switch. The KSZ8795-POE-EVAL board is designed to allow the user to experience
Gigabit up-link with KSZ9031 Gigabit PHY to Gigabit port of any processor board directly, and
can provide PoE PSE power to other four ports. Other rich feature set can be evaluated on this board.
The evaluation board is highly configurable and easy to use.
