Regulator Control
The ET1011C digital and analog core operates at 1.0 V. The analog I/O operates at 2.5 V. The digital I/O can operate at either
3.3 V or 2.5 V. The GMII interface operates at 3.3 V and the RGMII interface operates at 2.5 V. The on-chip regulator control
allows the device to be operated from a wide variety of external supply combinations. When more than one external supply is
available, one or both of the regulator control circuits may be left unused.
Table 16 lists example combinations of available external supplies and shows how the on-chip regulator control may be used
to provide the required supplies.
