KSZ9563RNXI

Controllers Overview

The KSZ9563RNXI is a 3-port Gigabit Ethernet switch manufactured by Microchip Technology, housed in a 64-pin VQFN (8 x 8mm) lead-free package. It integrates two 10/100/1000BASE-T PHYs and one configurable MAC port supporting RGMII, MII, or RMII interfaces. The device features a non-blocking wire-speed switching fabric with a 128kByte frame buffer and a 4096-entry forwarding table. It supports IEEE 1588v2 Precision Time Protocol (PTP), Audio Video Bridging (AVB), VLANs, QoS, and Energy-Efficient Ethernet (EEE). Operating temperature range is -40°C to +85°C.

Controllers Feature Summary

• Integrates two 10/100/1000BASE-T physical layer transceivers and one configurable external MAC port for direct host processor connection.
• Provides hardware support for IEEE 1588v2 PTP and AVB standards, including sub-microsecond synchronization and credit-based traffic shaping.
• Offers comprehensive Layer-2+ management capabilities including ACL filtering, RSTP/MSTP spanning tree protocols, and 128 active VLAN groups.

Controllers Applications

• Industrial Ethernet networks such as Profinet, MODBUS, and Ethernet/IP
• Real-time Ethernet control and automation switches
• Networked measurement and test equipment

Controllers Procurement Notes

Verify the suffix 'I' confirms the industrial temperature rating of -40°C to +85°C. Confirm the 'NX' suffix corresponds to the 64-pin VQFN package. Ensure the specific revision matches the required datasheet version DS00002319A. Check for any applicable errata sheets that may detail operational differences or recommended workarounds for this silicon revision.

Controllers Selection Notes

Select this component when a compact solution is required for three Gigabit ports with integrated PHYs. It is suitable for designs needing precise time synchronization via IEEE 1588v2 or high-quality audio/video streaming via AVB. The flexible MAC port allows direct interfacing with various host processors or FPGAs without additional PHY components.
