KSZ9567RTXI

Controllers Overview

The KSZ9567RTXI-TR is a 7-port Gigabit Ethernet switch from Microchip Technology, housed in a 128-pin TQFP-EP package. It integrates five 10/100/1000BASE-T PHY transceivers and two configurable MAC ports supporting RGMII, MII, or RMII interfaces. The device supports data rates of 10 Mb/s, 100 Mb/s, and 1 Gb/s with full and half duplex operation. Operating voltage ranges from 1.8 V to 3.465 V, with a maximum power current of 750 mA. It functions within an industrial temperature range of -40°C to +85°C.

Controllers Feature Summary

• Supports IEEE 1588v2 Precision Time Protocol and Audio Video Bridging standards for synchronized network operations.
• Includes non-blocking wire-speed switching fabric with extensive VLAN, QoS, and ACL filtering capabilities.
• Provides flexible management via SPI, I2C, MIIM, and in-band protocols alongside Wake-on-LAN power features.

Controllers Applications

• Industrial Ethernet networks including Profinet, MODBUS, and Ethernet/IP
• IEC 61850 power substation automation systems
• Real-time control and measurement equipment

Controllers Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm the component meets RoHS compliance requirements for your assembly process. Ensure the industrial temperature rating aligns with your environmental specifications. Cross-reference the datasheet revision to confirm silicon compatibility.

Controllers Selection Notes

Select this model when seven physical ports are required with integrated PHYs. Choose the KSZ9567R over managed switches lacking hardware timestamping if PTP synchronization is critical. Verify that the host processor supports the necessary interface modes like RGMII or RMII for the external MAC ports.

Controllers Part Context

This component belongs to the KSZ9567R series of managed Gigabit Ethernet switches. It is designed for high-performance industrial networking applications requiring deterministic latency and precise time synchronization across multiple connected devices.
