The Microchip KSZ8775CLX series of highly integrated, Layer 2-managed, five-port switch come with numerous features designed to reduce system cost. It is intended for cost-sensitive applications requiring three 10/100 Mbps 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.
