KSZ9563RNXI-TR

Controllers Overview

The KSZ9563RNXI-TR is a 3-port Gigabit Ethernet switch manufactured by Microchip Technology, featuring two integrated 10/100/1000BASE-T PHYs and one configurable MAC port with RGMII/MII/RMII interface. It supports IEEE 1588v2 PTP and AVB standards for precise time synchronization. The device operates within an industrial temperature range of -40°C to +85°C and utilizes a 64-pin VQFN package measuring 8x8mm. Power supply requirements include 1.8V, 2.5V, and 3.3V rails. Data rates support 10Mb/s, 100Mb/s, and 1Gb/s transmission speeds.

Controllers Feature Summary

• Non-blocking wire-speed switching fabric with hardware timestamping for IEEE 1588v2 and AVB applications
• Integrated management capabilities including VLAN, QoS, ACL filtering, and spanning tree protocols
• Flexible power management features supporting Energy-Efficient Ethernet and Wake-on-LAN standby modes

Controllers Applications

• Industrial Ethernet networks such as Profinet, MODBUS, and Ethernet/IP
• Real-time control systems requiring sub-microsecond synchronization
• Networked measurement and automation equipment

Controllers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the exact temperature grade and packaging configuration. The 'I' suffix indicates industrial temperature rating while '-TR' denotes tape and reel packaging. Ensure compatibility with host voltage levels before procurement.

Controllers Selection Notes

Select this component when designing systems requiring managed Gigabit switching with deterministic latency. The integrated PHYs simplify board layout compared to discrete solutions. Verify that the host processor supports the required RGMII or MII interface signals for proper connectivity.

Controllers Part Context

This part belongs to the KSZ9563 family of highly integrated Layer 2+ managed switches. It is designed to offload processing from the main host controller. The device integrates MAC and PHY functions to reduce system complexity and component count in industrial networking designs.

Controllers Replacement Considerations

Consult official substitution lists for compatible alternatives. Verify pinout and register compatibility if replacing existing components in established designs.
