SI3462-E04-GMR

Overview

The SI3462-E04-GMR is a single-port Power over Ethernet (PoE) Powered Device (PD) controller manufactured by Skyworks Solutions Inc. It complies with IEEE 802.3at and 802.3af standards. The device operates within an input voltage range of 2.7V to 3.3V and supports programmability features. It is housed in an 11-pin QFN EP package with dimensions of 3mm x 3mm x 0.83mm. The component functions as a PD controller, suitable for surface mount mounting, and operates between -40°C and 85°C.

Feature Summary

• Supports IEEE 802.3at and 802.3af PoE standards
• Integrated programmable control logic
• Compact 11-pin QFN EP surface-mount package

Applications

• Single-port PoE powered devices
• IEEE 802.3at compliant network endpoints
• IEEE 802.3af compliant network endpoints

Procurement Notes

Verify the specific suffix 'E04' against official Skyworks documentation to confirm it denotes the PD controller variant rather than the PSE variant found in other SI3462 subtypes. Ensure the package marking matches the 11-pin QFN specification. Confirm RoHS compliance status directly from the manufacturer's current datasheet revision.

Selection Notes

Select this component for designs requiring a dedicated PD controller for single Ethernet ports. Ensure the system power budget aligns with the 2.7V to 3.3V operating range. Verify that the PCB layout accommodates the 3x3mm QFN footprint and thermal pad requirements specified in the mechanical drawings.

Part Context

This part belongs to the SI3462 family of PoE controllers. While some sources list similar SKUs as PSE controllers, the E04 suffix typically identifies the PD controller version in Skyworks nomenclature. It serves as a key interface for managing power negotiation and delivery in PoE-enabled networking equipment.

Replacement Considerations

Check for direct pin-to-pin replacements within the SI3462 series or newer Skyworks PoE controller generations. Verify compatibility with existing IEEE 802.3at/af implementations before substituting.
