DP83867IR: 2/3 Power supply configuration in DP83867IRRGZR IC

Tool/software:

Hi, can I know the reason why there is a option of whether we can use 1.8 power supply or not as 2/3 supply configuration. Is there a specific reason behind this option?

    Hi Jainam, 

    The option to use two/three-supply configuration is to save overall power when three power supply configuration is used. The difference between two and three supply configuration is the internal LDO difference. 

    Best,
