±15kV ESD Protected MII/RMII 10/100 Ethernet Transceiver with HP Auto-MDIX Support and flexPWR® Technology in a Small Footprint
Datasheet
Note: For VDDIO operation below +2.5V, SMSC recommends designs add external strapping
resistors in addition the internal strapping resistors to ensure proper strapped operation.
