VSC8531XMW

Overview

The VSC8531XMW is a single-port copper Gigabit Ethernet PHY transceiver manufactured by Microchip Technology. It supports IEEE 802.3 standards including 10/100/1000BASE-T and 100BASE-TX, with data rates of 10 Mb/s, 100 Mb/s, and 1 Gb/s. The device features RGMII and RMII interface types for host connectivity. It operates within a supply voltage range of 950 mV to 1.05 V and functions at temperatures from 0°C to +125°C. Housed in a QFN-48 package, it supports full and half duplex modes.

Feature Summary

• Supports SyncE functionality for synchronization applications
• Integrates a single copper Gigabit Ethernet transceiver
• Compatible with RGMII and RMII host interfaces

Applications

• Industrial networking equipment requiring extended temperature ranges
• Telecommunications infrastructure utilizing SyncE
• Embedded systems with limited power supply headroom

Procurement Notes

Verify the specific suffix against official datasheets to confirm functional differences, as variants like -01 and -02 may differ in electrical specifications or packaging. Confirm RoHS compliance status directly from the manufacturer's documentation before procurement. Ensure the selected variant matches the required operating voltage and interface constraints for the target design.

Selection Notes

Select this component when a single-port solution with SyncE support is required. Compare the -01 and -02 variants carefully regarding voltage limits and supported standards. Ensure the host system provides the necessary 1.0V core voltage for the -01 variant or up to 3.3V for the -02 variant. Verify QFN-48 footprint compatibility during PCB layout.

Part Context

This part belongs to the VSC8531 series of Ethernet PHYs. It differs from multi-port devices like the VSC8514XMK, which offers four ports via QSGMII/SerDes. The VSC8531XMW focuses on single-port efficiency with specific voltage and interface optimizations compared to broader family members.
