KSZ8794CNXIC

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

KSZ8794CNX是高度集成的第2层管理的四端口交换机，具有许多旨在降低系统成本的功能。它适用于需要三个10/100Mbps铜缆端口和一个10/100/1000Mbps千兆上行端口的成本敏感型应用。

KSZ8794CNX具有小封装外形、低功耗、内部偏置和片内端接特性。其广泛的功能集包括增强的电源管理、可编程速率限制和优先级比率、标记的和基于端口的VLAN、基于端口的安全性和基于ACL规则的包过滤技术、具有四个队列的QoS优先级、管理接口、增强的MIB计数器、高性能内存带宽以及具有无阻塞支持的基于共享内存的交换机结构。

KSZ8794CNX支持多CPU数据接口，可有效应对当前和新兴的快速以太网和千兆以太网应用，其中GMAC接口可配置为RGMII、MII和RMII模式中的任何一种。KSZ8794CNX基于Microchip最新的行业领先的以太网模拟和数字技术，具有旨在卸载主机处理和简化整体设计的功能:

-三个集成的10/100ba se-T/TX MAC/phy
-一个集成的10/100/1000Base-T/TX GMAC，具有可选的RGMII、MII或RMII接口
-小型64引脚QFN封装
