Product Description
Microchip KSZ9897RTXI is a fully integrated layer 2 managed seven-port gigabit Ethernet switch designed for advanced networking applications. It supports 3.3 V power supply with a maximum data rate of 100 Mbps and uses RGMII interface for communication in both full duplex and half duplex modes. It includes five integrated 10/100/1000 Mbps PHYs and two configurable ports with SGMII, RGMII, MII, or RMII interfaces.
The device offers non-blocking wire-speed Ethernet switching fabric, enabling efficient data forwarding and filtering. Its features include comprehensive VLAN support with tag insertion/removal, support for double tagging, and a broad range of VLAN IDs allowing sophisticated network segmentation and security.
Full-duplex flow control and half-duplex backpressure mechanisms ensure smooth traffic management and collision control on networks. It supports multicast packet filtering via IGMPv1/v2/v3 snooping and IPv6 multicast listener discovery (MLD) snooping, enhancing multicast traffic efficiency.
Quality of Service (QoS) features prioritize critical packets using the 802.1p standard, making it suitable for networks requiring differentiated traffic handling. The switch is rated for operation across broad industrial temperature ranges (-40°C to 85°C), ensuring robust performance in demanding environments.
The compact 128-pin TQFP surface mount package (16 mm length × 16 mm width × 1.2 mm height) supports space-constrained PCB designs. The KSZ9897RTXI is manufactured in the United States, reflecting strict quality control standards.
Integrates a managed 7-port 10/100/1000 Layer-2 Ethernet switch with Gigabit uplink. Flexible interface configurations including RGMII, SGMII, MII, or RMII on designated ports. Advanced switching with VLAN, ACL filtering, and multicast snooping capabilities.
Robust flow control for full and half duplex modes. Designed for industrial and embedded networking applications. Explore more advanced Ethernet Transceiver solutions within our comprehensive semiconductor portfolio at EnvMart.
