KSZ9893R 2.0 INTRODUCTION 2.1 General Description
The KSZ9893R is a highly-integrated, IEEE 802.3 compliant networking device that incorporates a layer-2+ managed Gigabit Ethernet switch, two 10BASE-T/100BASE-TX/1000BASE-T physical layer transceivers (PHYs) and associated MAC units, and one MAC port with a configurable RGMII/MII/RMII interface for direct connection to a host processor/ controller, another Ethernet switch, or an Ethernet PHY transceiver. The KSZ9893R is built upon industry-leading Ethernet technology, with features designed to offload host processing and streamline the overall design: • Non-blocking wire-speed Ethernet switch fabric • Full-featured forwarding and filtering control, including port-based Access Control List (ACL) filtering • Full VLAN and QoS support • Traffic prioritization with per-port egress queues and by traffic classification • RSTP and MSTP Spanning Tree support • IEEE 802.1X port-based authentication support A host processor can access all KSZ9893R registers for control over all PHY, MAC, and switch functions. Full register access is available via the integrated SPI or I2C interfaces, and by in-band management via any one of the data ports. PHY register access is provided by a MIIM interface. Flexible digital I/O voltage allows the MAC port to interface directly with a 1.8/2.5/3.3V host processor/controller/FPGA. Additionally, a robust assortment of power-management features including IEEE 802.3az Energy-Efficient Ethernet (EEE) for power savings with idle link, and Wake-on-LAN (WoL) for low power standby operation, have been designed to satisfy energy-efficient system requirements. The KSZ9893R is available in commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges. An inter- nal block diagram of the KSZ9893R is shown in Figure 2-1.
