The VSC8530XMW-05 is a single-circuit Ethernet PHY from Microchip, designed for systems that communicate over RMII (Reduced Media-Independent Interface) to the MAC layer. Its function is Ethernet, and the RMII interface cuts the pin count compared to a full MII, which simplifies routing on cost-sensitive two-layer boards. The exposed paddle also serves as the primary ground return for the PHY.
Sourced per RFQ against your target quantity. The tray package is the standard delivery format for this QFN. If your pick-and-place line prefers tape-and-reel, confirm availability with your quote request — the tray is the listed option.
Design-in checklist – supply, layout, and thermal
Surface-mount on a 48-VFQFN exposed-pad package — the PCB land pattern should follow the supplier's recommended footprint to avoid solder bridging. The single-circuit PHY handles one Ethernet link. For multi-port designs, each port needs its own VSC8530XMW-05 or a multi-PHY device from the same family.
