For the Industrial Ethernet PHY transceiver:
• The Ethernet PHY requires two separate power sources. VDDIO is the 3.3 V, system generated analog
supply. VSYS_IO_3V3 is the 3.3V I/O supply.
• The Ethernet PHY is set to ENHANCED mode by pulling the MODESELECT pin up to VDDIO.
– ENHANCED mode allows the DP83826E to support real-time Ethernet applications in addition to standard
Ethernet applications.
• The Ethernet PHY uses many functional pins as strap options to place the device into a specific mode of
operation. Each functional pin has a default mode that is driven by an internal pull resistor
