SI3460-E03-GMR

Overview

The SI3460-E03-GMR is a single-port Power over Ethernet (PoE) Powered Device (PD) interface controller manufactured by Skyworks Solutions. It integrates a DC-DC converter and complies with the IEEE 802.3at standard, supporting up to 25.5W of power delivery. The device operates within a supply voltage range of 2.7V to 57V and functions reliably across an industrial temperature range from -40°C to +85°C. Packaged in a QFN-24 surface-mount format, it features a maximum duty cycle of 75% and includes humidity sensitivity protection for robust deployment.

Feature Summary

• Integrates a complete PD interface with an internal DC-DC converter for efficient power management
• Complies with IEEE 802.3at standards to support high-power applications up to 25.5W
• Operates over a wide input voltage range suitable for various PoE network environments

Applications

• Single-port PoE powered devices requiring integrated power conversion
• Industrial networking equipment operating in extended temperature ranges
• High-power IoT endpoints and edge computing nodes

Procurement Notes

This component is currently classified as having restricted supply availability. Distributors may not stock this part number, and orders might be subject to factory special requests or limited allocations. Verify current stock status and lead times directly with authorized suppliers before finalizing procurement plans due to potential discontinuation risks.

Selection Notes

Select this component when designing single-port PoE systems that require compliance with the 802.3at standard and need integrated DC-DC conversion capabilities. Ensure the application environment supports the specified operating temperature range and voltage limits. Consider the QFN-24 package constraints for thermal management and PCB layout requirements during the design phase.

Part Context

The SI3460-E03-GMR belongs to the Si3460 series of hot-swap voltage controllers and PoE interfaces. It serves as a specialized solution for managing power delivery in Ethernet-based networks. This part complements other Skyworks PoE products, such as PSE controllers, to provide comprehensive power management solutions for modern networking infrastructure.

Replacement Considerations

The SI3462-E01-GMR is listed as a possible replacement option. However, verify functional compatibility as the SI3462 is identified as a PSE controller rather than a PD interface. Confirm if the substitute meets specific system requirements before implementation.
