The KSZ8794CNX is a highly integrated, Layer 2 managed, four-port switch with numerous features designed to reduce system cost. It is intended for cost-sensitive applications requiring three 10/100Mbps copper ports and one 10/100/1000Mbps Gigabit uplink port.

The KSZ8794CNX incorporates a small package outline, low power consumption with internal biasing, and on-chip termination. Its extensive features set includes enhanced power management, programmable rate limiting and priority ratio, tagged and port-based VLAN, port-based security and ACL rule-based packet filtering technology, QoS priority with four queues, management interfaces, enhanced MIB counters, high-performance memory bandwidth, and a shared memory-based switch fabric with non-blocking support.

The KSZ8794CNX provides support for multiple CPU data interfaces to effectively address both current and emerging fast Ethernet and Gigabit Ethernet applications where the GMAC interface can be configured to any of RGMII, MII and RMII modes. The KSZ8794CNX is built on Microchip's latest industry-leading Ethernet analog and digital technology, with features designed to offload host processing and streamline your overall design:

• Three integrated 10/100Base-T/TX MAC/PHYs

• One integrated 10/100/1000Base-T/TX GMAC with selectable RGMII, MII or RMII interfaces

• Small 64-pin QFN package

A robust assortment of power management features including Energy Efficient Ethernet (EEE), PME and WoL have been designed in to satisfy energy efficient environments. All registers in the MAC and PHY units can be managed through the SPI interface. MIIM PHY registers can be accessed through the MDC/MDIO interface.
