VSC8502XML

Overview

The VSC8502XML-03 is a dual-port copper media PHY designed for space-constrained 10/100/1000BASE-T applications. It features integrated line-side termination to conserve board space and reduce EMI, alongside integrated RGMII timing compensation that eliminates the need for on-board delay lines. The device supports IEEE 802.3az Energy Efficient Ethernet (EEE) with Wake-on-LAN power management. It provides fast link failure indication in less than 1ms and supports Synchronous Ethernet and Ring Resiliency with programmable clock squelch. Operating temperatures range from -40°C ambient to 125°C junction. It is available in a 12 mm x 12 mm, 135-pin multi-row QFN package.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature range and package details. Ensure compatibility with required voltage domains and interface standards before procurement. Check for any recent product change notifications or end-of-life notices directly from Microchip Technology.

Selection Notes

Select this component when integrated line-side termination and reduced board space are critical requirements. Verify that the MAC interface supports RGMII version 1.3 or 2.0, or GMII/MII modes. Confirm that the operating environment falls within the specified temperature range of -40°C to 125°C junction.

Part Context

The VSC8502XML-03 belongs to the VSC8502 series of dual-port copper media PHYs from Microchip Technology. This series is engineered for compact networking solutions requiring high performance and low electromagnetic interference through integrated circuit design.

Replacement Considerations

Consult the official Microchip Technology documentation for verified substitute part numbers. Do not assume cross-compatibility with other PHY families without explicit datasheet confirmation.
