Microchip KSZ9897STXI-TR: A High-Performance, 7-Port Gigabit Ethernet Switch with Integrated PHYs

In the rapidly evolving landscape of network infrastructure, the demand for robust, high-performance, and highly integrated switching solutions continues to grow. The Microchip KSZ9897STXI-TR stands out as a premier solution, engineered to meet the rigorous demands of modern industrial, enterprise, and carrier applications. This highly integrated 7-port Gigabit Ethernet switch combines advanced management features with a high level of integration, simplifying design and reducing the total bill of materials for next-generation networking equipment.

At its core, the KSZ9897STXI-TR is a fully integrated Layer 2 managed switch featuring seven 10/100/1000BASE-T ports, each with its own Physical Layer transceiver (PHY). This integration is a key advantage, eliminating the need for external PHYs and thereby saving significant board space, reducing design complexity, and lowering overall system power consumption. The device is built on a mature and reliable architecture, ensuring robust data transmission and high interoperability with other network components.

A standout feature of this switch is its comprehensive suite of management and security functionalities. It supports advanced features such as IEEE 802.1Q VLAN for network segmentation, Quality of Service (QoS) with priority queues to ensure low latency for critical traffic, and IGMP snooping for efficient multicast traffic management. For security, it offers Access Control List (ACL) capabilities, port-based authentication, and various security features to safeguard network integrity.

Designed for resilience, the switch incorporates advanced energy efficiency technologies like IEEE 802.3az Energy-Efficient Ethernet (EEE), which minimizes power consumption during periods of low data activity. This makes it an ideal choice for environmentally conscious and power-sensitive applications. Its industrial temperature range support ensures reliable operation even in harsh environments, a critical requirement for industrial automation, surveillance systems, and outdoor equipment.

The KSZ9897STXI-TR also offers multiple operational modes for flexibility, including sophisticated traffic prioritization and rate limiting, giving network administrators precise control over their data flow. Its support for various interface options, such as RMII, RGMII, and MII, provides designers with the flexibility to connect to a wide range of host processors or other Ethernet controllers.

ICGOO FIND: The Microchip KSZ9897STXI-TR is a highly integrated and feature-rich 7-port Gigabit Ethernet switch that delivers exceptional performance, management capabilities, and design flexibility. Its combination of integrated PHYs, advanced Layer 2 features, and industrial robustness makes it a superior choice for developers building efficient, reliable, and secure networked systems.
