Microchip Technology KSZ8864 4 端口开关
Microchip Technology KSZ8864 4 端口开关是高度集成的第 2 层管理型开关，设计精良，采用小型封装并具有丰富的功能。KSZ8864 设计用于成本敏感型 10/100Mbps 4 端口开关系统，具有片上终端和低功耗特性，可节省系统成本。该开关设有 1.4Gbps 高性能内存带宽、基于共享内存的开关结构，并采用完全非阻塞配置。KSZ8864 提供广泛的功能集，例如电源管理、可编程速率限制和优先级比。其他特性包括基于标记/端口的VLAN、数据包过滤、服务质量 (QoS)、四个队列优先级、管理接口和MIB计数器。
The KSZ8864 contains four MACs and two PHYs. The two PHYs support the 10/100Base-T/TX. All registers of MACs and PHYs units can be managed by the control interface of SPI or the SMI. MIIM registers the PHYs can be accessed through the MDC/MDIO interface. EEPROM can set all control registers by the I2C controller interface for the unmanaged mode.
The Microchip Technology KSZ8864 4-Port 10/100 Managed Ethernet Switch is offered in a compact QFN-64 package and is AEC-Q100 qualified for automotive applications.
