KSZ8775

The KSZ8775CLX is a highly integrated, Layer 2-managed, five-port switch with numerous features designed to reduce system cost. It is intended for cost-sensitive applications requiring three 10/100Mbps copper ports, one RMII on Port 4, and one 10/100/1000Mbps Gigabit uplink port on Port 5.

The KSZ8775CLX incorporates a small package outline, the lowest power consumption with internal biasing, and on-chip termination. Its extensive set of features include 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 KSZ8775CLX provides support for multiple CPU data interfaces to effectively address both current and emerging fast Ethernet and Gigabit Ethernet applications where the Port 5 GMAC can be configured to any of the RGMII, MII, and RMII modes.

The KSZ8775CLX product is built upon Microchip's industry-leading Ethernet analog and digital technology, with features designed to offload host processing and streamline the overall design.

- Three integrated 10/100Base-T/TX MAC/PHYs
- One integrated 10/100Base-T/TX MAC with RMII interface
- One integrated 10/100/1000Base-T/TX GMAC with selectable RGMII, MII, and RMII interfaces
- Small 80-pin LQFP package

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

Microchip's complimentary and confidential LANCheck® online design review service is available for customers who have selected our products for their application design-in. The is subject to Microchip's and requires a myMicrochip account.
