VSC8514XMK-03

Overview

The VSC8514XMK-03 is a quad-port Gigabit Ethernet transceiver manufactured by Microchip Technology. It supports 10/100/1000BASE-T communication over Category 5 unshielded twisted pair cables. The device features a QSGMII SerDes MAC interface and integrated line-side termination resistors. It operates with 1.0 V and 2.5 V power supplies, supporting 3.3 V-tolerant I/Os. Operating temperatures range from -40 °C to 125 °C junction. The component is housed in a 138-pin multi-row plastic QFN package measuring 12 mm x 12 mm.

Feature Summary

• Supports Ring Resiliency for switching between master and slave timing references without link drop in 1000BASE-T mode.
• Includes EcoEthernet 2.0 technology for Energy Efficient Ethernet and power saving based on link state.
• Features fast link failure indication identifying link onset in less than 1 ms typical.
• Provides VeriPHY cable diagnostics and HP Auto-MDIX support.

Applications

• Synchronous Ethernet (SyncE) applications requiring ITU-T G.8261/Y.1361 compliance.
• High-availability networks utilizing fast link failure indication.
• Systems requiring inline-powered device detection for IP phones or wireless access points.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature range and package variations. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure compatibility with the target system's management bus and clock requirements.

Selection Notes

Select this component for designs requiring four copper media ports with a single QSGMII interface. Consider the integrated line driver and termination resistors for PCB space conservation. Verify that the application environment supports the specified junction temperature limits and power supply voltages.

Part Context

This part belongs to the VSC8514 series of low-power Gigabit Ethernet transceivers. It utilizes mixed signal and digital signal processing architecture for robust performance. The device is compliant with IEEE 802.3 standards for 10BASE-T, 100BASE-TX, and 1000BASE-T.

Replacement Considerations

Consult official substitution lists for verified alternatives. Generic cross-references may not match the specific QSGMII interface or proprietary features like Ring Resiliency.
