KSZ9567RTXI-TR Présentation
An Ethernet switch is a semiconductor device that connects multiple network nodes and forwards Ethernet frames according to Layer 2 MAC addresses. A managed gigabit switch adds port configuration, monitoring, traffic prioritization, and diagnostic controls. In the broader network hierarchy, the KSZ9567 is a highly integrated Ethernet interface IC combining switch fabric, copper PHYs, serial interfaces, clocking, and management functions within one device.
Five of the seven ports integrate 10/100/1000 Mbps PHYs. The remaining two ports can be configured as SGMII or RGMII, MII, or RMII interfaces according to the manufacturer product description and datasheet. Verified distributor listings identify I2C and SPI interfaces, while listed management and network features include IEEE 1588 v2, Audio Video Bridging, Energy Efficient Ethernet, Wake-on-LAN, QoS, LinkMD, and industrial-temperature operation.
The KSZ9567R uses configuration strap pins to establish operating modes. According to the verified Microchip datasheet, RESET_N must be low while these pins are high impedance, allowing external pull-up or pull-down resistors to create configuration states that are sampled on the rising edge of RESET_N. This makes board-level mode selection deterministic, but every strap, reset, and supply connection must follow the datasheet reference circuit.
Typical uses include industrial Ethernet gateways, networked automation equipment, embedded servers, communications infrastructure, and managed network interfaces requiring multiple gigabit ports in one package. Consolidating five PHY ports and two configurable interfaces reduces component count, but careful decoupling, controlled clocking, exposed-pad thermal management, and high-speed layout remain essential.
Designers should use the manufacturer reference schematic and layout guidance, place high-frequency decoupling close to supply pins, provide a continuous thermal path through the exposed pad, and observe Ethernet magnetics and routing requirements. Firmware, management, and register compatibility must also be reviewed because a managed Ethernet switch is a system-level component rather than a simple physical-layer transceiver.
This page consolidates verified manufacturer and distributor information, source links, application guidance, and replacement analysis. It also distinguishes electrically similar devices from verified pin-to-pin drop-in alternatives, helping engineers assess PCB reuse without treating package similarity as proof of compatibility.

Applications typiques
KSZ9567RTXI-TR convient pour 6 applications: Industrial Ethernet Gateway, Managed Network Switch, Industrial Automation Controller, Embedded Communications Equipment, Networked Audio/Video Endpoint, Industrial Test and Measurement System.
Industrial Ethernet Gateway
The KSZ9567RTXI-TR fits an industrial gateway that must consolidate multiple wired network nodes without using separate Ethernet PHYs. Five ports integrate 10/100/1000 Mbps copper PHYs, while two additional ports support configurable SGMII or RGMII, MII, or RMII connections. This mixed interface flexibility allows one Layer 2 device to serve copper ports and an uplink or expansion fabric. I2C and SPI provide embedded host-control options, while QoS, LinkMD, and IEEE 1588 v2 support traffic prioritization, diagnostics, and synchronization. The principal trade-off is design complexity: the 128-pin exposed-pad TQFP requires careful high-speed layout and thermal implementation.
Recommandé
Managed Network Switch
The KSZ9567RTXI-TR provides the core switching fabric for a compact managed Ethernet system with seven configurable network paths. Its Layer 2 architecture, QoS, LinkMD, IEEE 1588 v2, and Audio Video Bridging features go beyond a basic unmanaged switch and can support equipment needing priority traffic, link diagnostics, timing, or synchronized media. Five integrated gigabit copper PHYs reduce the number of external physical-layer devices, while the two configurable interfaces can serve an uplink. Firmware and management-register compatibility must be validated because switching behavior can differ even when the physical interfaces match.
Recommandé
Industrial Automation Controller
The KSZ9567RTXI-TR is suitable for automation equipment requiring several Gigabit Ethernet connections alongside real-time or deterministic network behavior. IEEE 1588 v2 supports precise network timing, QoS helps protect priority traffic, and LinkMD assists link diagnostics. Five integrated copper PHYs can connect local controllers, sensors, HMIs, and service networks, while the two flexible interfaces provide options for an uplink or alternate MAC/PHY connection. The industrial-temperature listing is relevant for factory equipment, but the final thermal margin must be calculated from actual dissipation and the exposed-pad layout documented by Microchip.
Recommandé
Embedded Communications Equipment
KSZ9567RTXI-TR can serve as the network backbone inside embedded communications equipment where seven ports and multiple media options are valuable. Five 10/100/1000 Mbps PHYs support direct copper links, while the two configurable ports can use serial Ethernet interfaces for other PHYs or fabric connections. I2C and SPI permit connection to an embedded processor, and WOL can support remote activation. Compared with a collection of discrete PHYs and a separate switch, the integrated device can simplify interconnects and board space, but firmware ownership and long-term configuration control must be included in the product design.
Recommandé
Networked Audio/Video Endpoint
Audio Video Bridging support makes the KSZ9567RTXI-TR relevant to networked audio/video equipment that needs multiple Gigabit Ethernet links and managed Layer 2 behavior. Five copper ports can connect displays, speakers, control surfaces, or nearby AV devices, while QoS can protect priority traffic and IEEE 1588 v2 can support synchronization. The two configurable interfaces provide additional uplink or expansion options. AVB support does not remove the need for correct firmware, buffering configuration, media-path latency budgets, and exact synchronization configuration, all of which must be validated in the complete endpoint design.
Recommandé
Industrial Test and Measurement System
A compact test or measurement instrument can use the KSZ9567RTXI-TR to provide several Gigabit Ethernet service and instrument connections. Five integrated copper PHYs support direct wired links, and the two additional configurable interfaces allow connection to a processor or test backplane. LinkMD assists link-status diagnosis, QoS can prioritize measurement data, and Wake-on-LAN supports remote access. For bench or laboratory equipment, Ethernet transformer selection, isolation, grounding, and enclosure EMC requirements remain important. The 128-pin TQFP exposed pad should be tied and thermally connected according to the manufacturer layout guidance.

Notes de conception
Treat the KSZ9567RTXI-TR as a high-speed mixed-signal design, not as a generic digital IC. Follow the manufacturer reference layout for the 128-pin TQFP exposed pad, Ethernet differential pairs, clock sources, decoupling, and configuration straps. Keep supply and ground connections short, place decoupling capacitors at the required pins, preserve continuous return paths beneath pairs, and avoid routing high-speed signals across split planes. Obtain the official reference design before finalizing layer stack-up and component placement.
Use only the power rails and sequencing specified in the Microchip KSZ9567R datasheet. Configuration straps are meaningful only in the specified reset sequence: while RESET_N is low they are high impedance, and their resistor-defined states are sampled on the rising edge of RESET_N. Confirm all pull-up and pull-down values, required supplies, power-on timing, reset behavior, and clock sources against the reference circuit. Do not infer strap logic from the ordering code or distributor summaries.
The 128-pin TQFP includes an exposed pad, but thermal performance depends on the PCB copper, thermal-via pattern, copper layers, airflow, and dissipated power. Use the manufacturer land pattern and vias rather than creating an ad hoc thermal pattern. Calculate dissipation from the actual rail voltages and operating modes for the five copper PHYs and other enabled functions, then verify junction temperature with the datasheet limits. Numeric power and thermal values were not supplied here and require datasheet extraction.
Do not assume that another seven-port Ethernet switch is interchangeable merely because it uses a QFP package. Firmware, register maps, interrupt behavior, PHY registers, strap configuration, serial-interface timing, clock requirements, and reference circuitry can differ even when the package has the same pin count. For a true drop-in decision, compare every pin, supply, clock, reset, strap, exposed-pad connection, media interface, and management function against both datasheets.
Validate Ethernet pair routing, clock quality, return loss, insertion loss, isolation boundaries, and magnetics selection in the final board stack-up. Keep each differential pair continuous with controlled impedance and minimize vias and stubs. Isolate noisy digital, switching-power, and high-speed serial-interface return currents from sensitive PHY paths. Compliance testing must use the complete product implementation because shielding, chassis grounding, connectors, and external magnics materially affect radiated and conducted Ethernet performance.
Informations de conformité
The supplied manufacturer and distributor snippets identify industrial temperature and tape-and-reel ordering information but do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. These fields remain unknown rather than inferred.
