KSZ8765CLX 1.0 INTRODUCTION 1.1 General Description
The KSZ8765CLX is a highly integrated, Layer 2-managed, five-port switch with numerous features designed to reduce overall system cost. It is intended for cost-sensitive applications requiring four 10/100 Mbps copper ports and one 10/ 100/1000 Mbps Gigabit uplink port. The KSZ8765CLX incorporates a small package outline, the lowest power consump- tion 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-per- formance memory bandwidth, and a shared memory-based switch fabric with non-blocking support. The KSZ8765CLX 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 GMII, RGMII, MII, and RMII modes. The KSZ8765CLX is built upon industry-leading Ethernet analog and digital technology, with features designed to off- load host processing and streamline the overall design. • Two integrated MAC/PHYs 100BASE-FX on Port 1 and Port 2 • Two integrated MAC/PHYs 10/100BASE-T/TX on Port 3 and Port 4 • One integrated 10/100/1000BASE-T/TX GMAC with selectable GMII, 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.
