4.2
The MPC8308_RDB board requires a power supply from the 4-pin power jack. It provides 12 V and 5 V
supply to the board. Core voltage, DDR2 voltage, RGMII voltage, and PHY-specific voltages are provided
by either switching or linear regulated depending on the voltage drop and current consumption
requirement.
