Procurement Notes

Verify the specific ordering suffix to ensure correct configuration, as variants like VSC8531XMW-02 exist within the same family. Confirm RoHS compliance status through official documentation before integration. Ensure ESD protection measures are implemented during handling due to moisture sensitivity classification. Validate that the 1.0V core voltage requirement aligns with the target system's power delivery network design.

Selection Notes

Select this component when a single-port Gigabit solution with low-voltage operation is required. The 48-lead QFN package suits space-constrained designs. Consider the 0°C to +125°C temperature range for industrial environments. Verify interface compatibility with the host processor, as both RGMII and RMII are supported. Ensure the system can provide the specified 950 mV to 1.05 V core supply.
