SI3460-E03-GM

Overview

The SI3460-E03-GM is a single-port Power over Ethernet (PoE) Powered Device (PD) interface controller manufactured by Skyworks Solutions. It integrates a DC-DC controller to support IEEE 802.3at Type 2 power delivery standards, enabling up to 13W of power consumption for connected loads. 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-20 surface-mount format, it provides a compact solution for PoE-enabled applications requiring efficient power management and protocol compliance.

Feature Summary

• Integrates a dedicated DC-DC controller for efficient power conversion in PoE PD applications
• Complies with IEEE 802.3at Type 2 standards for high-power data port connectivity
• Supports wide input voltage operation suitable for various PoE power sourcing equipment

Applications

• Single-port PoE powered devices requiring Type 2 power levels
• Network infrastructure endpoints with integrated power management
• IoT gateways and sensors utilizing high-power PoE interfaces

Procurement Notes

Verify the specific suffix E03 against the manufacturer's latest documentation to ensure compatibility with current production revisions. Confirm that the QFN-20 package dimensions align with the target PCB footprint. Check for any recent Product Change Notifications regarding material or manufacturing process updates. Ensure the design accounts for the component's humidity sensitivity rating during storage and reflow soldering processes.

Selection Notes

Select this component when designing single-port PoE systems requiring Type 2 power classification. It is suitable for applications needing integrated DC-DC control rather than discrete solutions. Consider the thermal performance of the QFN-20 package under maximum load conditions. Verify that the host system supports the required communication protocols for PD identification and power negotiation.

Part Context

This part belongs to the Si3460 series of PoE controllers designed for Powered Devices. It complements other Skyworks solutions like the SI3462 PSE controllers by providing the endpoint interface capability. The series focuses on simplifying PoE integration through combined interface and power management functions in a small form factor.

Replacement Considerations

Publicly documented potential substitutes include the SI3462-E01-GMR, though this is primarily a PSE controller. Direct functional replacements should be verified against the official datasheet cross-reference list. Ensure any substitute matches the 802.3at Type 2 specification and QFN-20 package.
