The KSZ8765 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 10/100Mbps copper ports and one 10/100/1000Mbps Gigabit uplink port.
The KSZ8765CLX incorporates a small package outline, low 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 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 Microchip's industry-leading Ethernet analog and digital technology, with features designed to offload 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.

电子发烧友网报道(文/李宁远)传感器作为感知周围环境的重要媒介,一直在诸多领域扮演着重要角色。和我们生活息息相关的气体传感,一直是传感器行业重要的细分领域,随着新材料,MEMS技术与电子电路技术的进步,气体传感也不断变化着。与此同时,不断发展的法规与安全标准对气体检测也提出了更严格的要求。 目前,按照技术原理气体传感器可划分为半导体气体传感器、催化燃烧气体传感器、电化学气体传感器、光学气体传感器等多种类型
Python程序文件的扩展名主要有两种,分别是.py和.pyw。 .py扩展名: .py是Python程序最常见的扩展名,它表示一个Python脚本文件。Python解释器会读取和执行.py文件中的代码。这种扩展名的文件可以在命令行中运行,或者通过其他程序调用执行。常见的用法是通过命令行运行:python filename.py。 .pyw扩展名: .pyw是Python窗口化程序的扩展名。与.py文件不同,.pyw文件在执行时不会产生一个命令行窗口。这意味着窗口化程序可以在后台运行,无需用户看到命令行窗口
