KSZ9563RNXC

Controllers Overview

The KSZ9563RNXC is a 3-port Gigabit Ethernet switch manufactured by Microchip Technology. 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 4096-entry forwarding table and 128kByte frame buffer. It supports IEEE 1588v2 PTP and IEEE 802.1AS AVB for precise time synchronization. Power management includes IEEE 802.3az EEE and Wake-on-LAN. The component operates within a commercial temperature range of 0°C to +70°C and is housed in a 64-pin VQFN (8x8mm) lead-free package.

Controllers Feature Summary

• Integrates two 10/100/1000BASE-T physical layer transceivers and one configurable MAC port for direct host processor connection.
• Provides hardware support for IEEE 1588v2 Precision Time Protocol and Audio Video Bridging standards for sub-microsecond synchronization.
• Includes comprehensive Layer-2+ managed switching capabilities such as VLAN, QoS, ACL filtering, and spanning tree protocols.

Controllers Applications

• Industrial Ethernet networks including Profinet, MODBUS, and Ethernet/IP
• Real-time Ethernet control systems
• Networked measurement and test equipment

Controllers Procurement Notes

Verify the ordering suffix 'C' confirms the commercial temperature range specification. Confirm the absence of the '-TR' suffix indicates standard tray packaging rather than tape and reel. Ensure the part number matches the specific package type required for the design layout.

Controllers Selection Notes

Select this component when a compact solution with integrated PHYs and high-precision time synchronization is required. The commercial temperature rating limits suitability for harsh environments compared to industrial variants. Verify interface compatibility with the host processor's available MAC ports.

Controllers Part Context

This model belongs to the KSZ9563RNX family of Gigabit Ethernet switches. The 'C' suffix denotes the commercial temperature operating range, distinguishing it from the 'I' suffix variant designed for industrial applications. The base device architecture remains consistent across these temperature grades.

Controllers Replacement Considerations

The KSZ9563RNXI serves as the industrial temperature equivalent. Other Microchip switches may offer different port counts or interface options but require verification of pinout and register compatibility.

Controllers FAQ

What types of interfaces are supported on the third port?

The third port supports configurable Reduced Gigabit Media Independent Interface (RGMII), Media Independent Interface (MII), and Reduced Media Independent Interface (RMII).

Does the device support cable diagnostics?

Yes, the integrated PHYs include LinkMD cable diagnostic capabilities to determine cable opens, shorts, and length.

How is the device managed?

Management is accessible via high-speed SPI, I2C, MIIM interfaces, or through-band management via any of the three data ports.
