KSZ8563RNXV - 3-Port 10/100 Ethernet Switch | Microchip
料号： KSZ8563RNXV ✓ 量产中KSZ8563RNXV 概述
An Ethernet switch is a network-semiconductor device that connects multiple Ethernet ports and moves frames according to MAC addresses while adding layer-2 management, prioritization, and traffic-management functions. The KSZ8563 combines two copper Ethernet PHYs with a configurable host interface, making it suitable for embedded systems that need to consolidate wired network connections without using a separate external switch.
Key features include three-port switching, integrated 10BASE-T and 100BASE-TX transceivers, IEEE 802.3 compliance, and support for RGMII, MII, and RMII host interfaces. IEEE 1588v2 and 802.1AS time synchronization, AVB traffic handling, Energy Efficient Ethernet, Wake-on-LAN, QoS, LinkMD+, and fault-recovery functions broaden its suitability for industrial, automotive, and communications equipment.
The configurable third MAC port allows a host processor or controller to connect through a parallel RGMII interface, MII interface, or lower-pin-count RMII interface. Management access through I2C or SPI supports software initialization, status monitoring, address-table administration, and switch configuration. These features combine hardware connectivity with firmware-controlled layer-2 functions in one package.
Typical uses include industrial Ethernet gateways, automotive head-unit networking, building-automation controllers, embedded network appliances, and factory equipment with multiple wired ports. A compact system design can use the two integrated PHY ports for external copper links while reserving the configurable MAC port for communication with a host processor.
PCB implementation requires careful attention to the 64-pin VQFN land pattern, exposed-pad thermal management, high-speed RGMII or RMII signal routing, and Ethernet magnetics or integrated magnetics connected to the copper PHY ports. Follow the manufacturer pin-description table and reference layout when assigning tracks and component placement.
This page combines the manufacturer device description, exact orderable-package information, interface and standards details, sourcing guidance, and practical implementation considerations into a compact engineering reference for evaluating the KSZ8563RNXV.

典型应用
KSZ8563RNXV 适用于 6 应用s: Industrial Ethernet Gateway, Automotive Head-Unit Networking, Factory Automation Controller, Building Automation Gateway, Embedded Network Appliance, Test and Measurement Instrument.
Industrial Ethernet Gateway
The KSZ8563RNXV fits industrial gateways that need to combine two external 10/100 links with a host-processor connection. Its configurable third port can use RGMII, MII, or RMII, allowing the controller interface to match processor capabilities and board constraints. IEEE 1588v2 and 802.1AS provide precise time synchronization, QoS prioritizes control traffic, and LinkMD+ assists cable diagnostics. The two integrated PHYs also reduce the external component count compared with a discrete switch arrangement.
推荐
Automotive Head-Unit Networking
The three-port KSZ8563RNXV architecture is suitable for a vehicle head unit or domain controller requiring two copper network connections and one host-facing interface. The configurable MAC port supports RGMII, MII, or RMII, while IEEE 1588v2 and 802.1AS support precise network timing across cooperating nodes. LinkMD+ and fault-recovery functions improve diagnostics after cabling disturbances. Confirm automotive qualification, temperature range, and the exact ordering suffix before production release.
推荐
Factory Automation Controller
The KSZ8563RNXV can centralize network connections in a factory automation controller while retaining synchronization across distributed equipment. Its two integrated 10BASE-T/100BASE-TX PHYs support copper links to sensors, drives, or remote I/O, and the configurable host port connects the switching function to an embedded processor. QoS can protect time-sensitive operational traffic, IEEE 1588v2 supports synchronized control, and LinkMD+ assists technicians in identifying cabling faults.
推荐
Building Automation Gateway
The KSZ8563RNXV is well suited to building-automation gateways that aggregate wired controller traffic and expose a host-management connection. EEE can reduce power consumption on lightly used links, WOL supports remote wake-up, and QoS can separate operational control traffic from less urgent data. With three ports in one 64-pin VQFN, a design can connect two field networks to a processor through RGMII, MII, or RMII without using three unrelated network components.
推荐
Embedded Network Appliance
The KSZ8563RNXV supports compact embedded appliances that need managed Ethernet switching rather than a simple repeater. Two integrated PHYs provide external copper connectivity, while the third configurable MAC port links to the appliance processor. Management through I2C or SPI enables software control of switch functions, address tables, QoS, and diagnostics. IEEE 1588v2, 802.1AS, and AVB features can support synchronized or multimedia traffic when the system design requires them.
推荐
Test and Measurement Instrument
The KSZ8563RNXV can support networked test equipment that must expose multiple Ethernet links while coordinating time-sensitive measurements. The configurable RGMII, MII, or RMII port connects the switch to an instrument controller, and IEEE 1588v2 with 802.1AS supports synchronized timing across distributed equipment. LinkMD+ and fault recovery improve diagnostics, while QoS can protect measurement-control traffic from background network activity.

设计说明
Route the configurable RGMII or RMII interface as a controlled-length, continuous-impedance digital bus, and place termination, series-resistance, and decoupling locations according to the manufacturer reference layout. Keep the two copper-PHY sections away from noisy switch-mode supplies and clocks. The 64-pin VQFN land pattern and exposed pad require exact footprint geometry; verify pin 1 and pad orientation against the package drawing before fabrication.
The 64-pin VQFN has a large exposed thermal pad, but its thermal performance depends on the PCB copper area, inner-layer copper, via pattern, and airflow. Use the maximum thermal-resistance conditions in the manufacturer datasheet when calculating junction rise. Follow the exposed-pad solder and assembly requirements, including the specified paste area and via pattern, to avoid voiding and uneven heating.
Treat the RGMII interface as a high-speed parallel bus and the copper channels as Ethernet differential pairs. Avoid adding stubs or unnecessary test pads to sensitive nets, and preserve the reference-plane path beneath each interface. Confirm magnetics or integrated-magnetics requirements for each external 10/100 port and use the manufacturer reference schematic for termination and network-side component placement.
Do not treat KSZ8563RNXV, KSZ8563RNXV-VAO, and other ordering variants as automatically equivalent. Verify the complete ordering table, temperature range, qualification status, exposed-pad design, and software-support assumptions before substitution. Likewise, a switch with similar port count is not a drop-in replacement unless its package, pin assignment, host interface, management register set, and PHY behavior have been verified.
