KSZ9567STXI - 7-Port Gigabit Ethernet Switch | Microchip
부품 번호: KSZ9567STXI ✓ 활성KSZ9567STXI 개요
A managed Gigabit Ethernet switch is a networking semiconductor that combines multiple physical-layer interfaces, frame processing, port management, and traffic-control functions on one die. Within the network hierarchy, the KSZ9567 belongs to Ethernet switches, network interface controllers, and integrated interface ICs. Integrating five copper PHYs with two configurable serial interfaces allows one device to connect several 10/100/1000BASE-T endpoints while also supporting uplink connections over SGMII or RGMII.
The principal feature of the KSZ9567STXI is its combination of five integrated Gigabit PHYs and two configurable interfaces in one managed Layer 2 device. IEEE 1588 v2 supports precise time synchronization, while AVB features address latency-sensitive audio and video traffic. EEE reduces power consumption when links are idle, Wake-on-LAN supports remotely waking networked equipment, QoS provides traffic prioritization, and LinkMD provides cable diagnostics.
Host control through I2C or SPI allows an embedded processor or system controller to configure switch registers, monitor port status, and implement network-management functions. The 128-TQFP-EP package provides a high pin count for the five integrated PHY interfaces, two configurable ports, digital management signals, clocks, power rails, and exposed-pad thermal construction. Industrial-temperature capability makes the device suitable for equipment expected to operate beyond typical commercial consumer environments.
Typical uses include industrial Ethernet equipment, automotive or transportation networking platforms, network bridges, embedded gateways, smart-building controllers, and test systems requiring multiple Gigabit Ethernet ports. A compact embedded system can use the five integrated PHYs for direct copper links while reserving the configurable ports for processor or switch-to-switch uplinks. IEEE 1588 v2 is particularly relevant to synchronized industrial and automotive networks, while AVB and QoS benefit real-time multimedia traffic.
PCB design should prioritize short, controlled-impedance connections around each integrated PHY and preserve the layout guidance in the manufacturer datasheet. Power and ground distribution must support all enabled PHYs, and the exposed pad requires the recommended thermal and assembly footprint. Firmware and host software should validate port configuration, link-speed negotiation, timestamp handling, and ring or redundancy behavior before field deployment.
This product page consolidates the verified port count, interface capabilities, management features, package information, replacement guidance, and application-oriented design considerations into an engineering-focused resource for switch, network-interface, and industrial-control designers.

일반적인 애플리케이션
KSZ9567STXI 적합 용도: 6 애플리케이션s: Industrial Ethernet Gateway, Automotive Network Gateway, Smart Building Controller, Industrial Camera Aggregator, Time-Synchronized Test Equipment, Network Bridge and Embedded Switch.
Industrial Ethernet Gateway
The KSZ9567STXI fits industrial gateways that need several local copper links and one or two high-speed uplinks. Its five integrated 10/100/1000 Mbps PHYs provide direct Ethernet connections for sensors, controllers, and service equipment, while the two configurable SGMII or RGMII ports can connect to a host processor or upstream switch. Managed Layer 2 operation, QoS, and LinkMD support controlled traffic handling and cable diagnostics. The industrial-temperature designation makes the device suitable for equipment operating outside typical consumer environments, subject to confirmation of the complete ordering code and the system’s thermal and power requirements.
추천
Automotive Network Gateway
The KSZ9567STXI is suitable for vehicle and transportation gateways requiring a consolidated Layer 2 switching function. Five integrated Gigabit PHYs can connect Ethernet-based vehicle domains, while the configurable SGMII or RGMII ports support processor-facing or uplink connections. IEEE 1588 v2 provides the timing foundation required by synchronized networks, and AVB can benefit latency-sensitive infotainment traffic. Design teams must still verify the ordering suffix’s automotive qualification, define the power architecture, and validate EMC, thermal, and network-isolation requirements for the final vehicle platform.
추천
Smart Building Controller
The KSZ9567STXI can consolidate wired building-network endpoints in a controller or edge gateway. Its five 10/100/1000 Mbps PHYs serve rooms, cameras, access-control equipment, and building-management nodes, while the two configurable ports provide uplink flexibility. QoS prioritizes operational traffic, EEE reduces link energy use, and Wake-on-LAN supports remotely accessed equipment. LinkMD assists with cable diagnostics in installations where wiring faults are common. The controller design should account for the device’s industrial-temperature rating, switch-management firmware, thermal dissipation, and system-level surge and EMC requirements.
추천
Industrial Camera Aggregator
The KSZ9567STXI supports camera and sensor aggregation where multiple wired endpoints must be connected to a higher-speed network fabric. Five integrated Gigabit PHYs provide direct links to cameras, while SGMII or RGMII can carry traffic toward a compute module or network uplink. QoS can separate time-sensitive video traffic from routine management traffic, and IEEE 1588 v2 is valuable when cameras and downstream processing require synchronized timing. Engineering validation should include cable-length limits, thermal performance with all PHYs active, firmware-based traffic shaping, and isolation testing for industrial camera installations.
추천
Time-Synchronized Test Equipment
The KSZ9567STXI is appropriate for test and measurement systems that require deterministic Ethernet transport, diagnostics, and multiple active links. IEEE 1588 v2 enables precise time synchronization across connected instruments or embedded nodes, while QoS helps isolate control traffic from high-volume test payloads. Five integrated PHYs reduce the number of discrete copper-interface devices needed for a multiport fixture. For laboratory equipment, validate clock sourcing, timestamp accuracy, thermal rise with sustained traffic, and the latency contribution of the managed Layer 2 path before using the switch as a precision timing resource.
추천
Network Bridge and Embedded Switch
The KSZ9567STXI can act as a compact network bridge or embedded switching node between copper devices and a serial Ethernet uplink. Its five integrated PHYs support direct 10/100/1000BASE-T connectivity, while two configurable ports allow SGMII or RGMII links to a host processor or another switching device. Wake-on-LAN supports remote endpoint activation, EEE lowers idle-link energy, and LinkMD helps identify cabling faults. A practical implementation requires careful management-plane firmware, correct buffer and QoS configuration, an uninterrupted exposed-pad thermal path, and layout compliance with the manufacturer’s high-speed Ethernet guidance.

설계 노트
Treat all five integrated PHY channels as high-speed differential interfaces. Follow the manufacturer’s reference layout for trace geometry, via transitions, return paths, and component placement, and avoid placing disruptive switching or isolation circuitry near the PHY lanes. The 14 x 14 mm 128-TQFP-EP footprint leaves limited routing space, so verify connector, magnetics, and decoupling placement against the manufacturer’s land pattern before release.
Calculate heat dissipation with all active PHYs, the selected SGMII or RGMII configuration, and the highest expected switching activity. Connect the exposed pad to the manufacturer-recommended ground plane and thermal-via pattern without compromising high-speed return paths. Use board copper and enclosure airflow as part of the thermal design, because package performance alone does not determine the junction-temperature margin.
Separate or carefully filter the supplies serving the digital core, PHY circuitry, clocks, and any external magnetics. Place required bypass capacitance at the package power pins and follow the manufacturer’s recommended values and layout to prevent supply disturbance from appearing at Ethernet line interfaces. Confirm startup sequencing, voltage tolerances, and peak current before assigning power-supply capacity.
Do not assume the STXI and RTXI ordering suffixes are interchangeable without checking temperature grade, qualification, and ordering information. Also validate that the selected firmware enables the intended SGMII or RGMII configuration, applies QoS and IEEE 1588 v2 parameters correctly, and interprets LinkMD results for the installed cable plant. These checks prevent PCB-level and network-management incompatibilities.
