KSZ9897RTXC

Controllers Overview

The KSZ9897RTXC is a 7-port Gigabit Ethernet managed switch IC from Microchip Technology, housed in a 128-pin TQFP-EP (14x14mm) package. It integrates five 10/100/1000BASE-T PHY transceivers and two configurable MAC ports supporting RGMII, MII, or RMII interfaces. The device operates within a commercial temperature range of 0°C to +70°C. Electrical specifications include a minimum supply voltage of 1.8V and a maximum of 3.465V, with a maximum power consumption of 750mA. Supported data rates are 10Mb/s, 100Mb/s, and 1Gb/s.

Controllers Feature Summary

• Non-blocking wire-speed switching fabric with store-and-forward architecture
• Integrated management capabilities including VLAN, QoS, and ACL filtering
• Flexible host interface options via SPI, I2C, MIIM, and in-band management

Controllers Applications

• Stand-alone 10/100/1000Mbps Ethernet switches
• VoIP infrastructure switches
• Broadband gateways and firewalls
• Wi-Fi access points
• Industrial control and automation switches

Controllers Procurement Notes

Verify the specific suffix 'XC' against official datasheets to confirm the commercial temperature rating and packaging type. Ensure compatibility with required voltage levels and interface configurations before integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Controllers Selection Notes

Select this component for designs requiring integrated Gigabit PHYs alongside configurable MAC interfaces. Consider the commercial temperature range suitability for the target environment. Evaluate power management features like Energy Detect and Wake-on-LAN if low-power operation is required.

Controllers Part Context

This part belongs to the KSZ9897R series, which includes industrial variants such as the KSZ9897RTXI. The RTXC variant specifically denotes the commercial temperature grade and tray packaging option, distinguishing it from reel-packaged or industrial-rated counterparts within the same functional family.

Controllers Replacement Considerations

KSZ9897STXI is an industrial-grade alternative with similar functionality but different temperature ratings.
