DP83867IS: Compare To KSZ9031RNX

Part Number: DP83867IS

Dear Team,

1. The customer want to know the efficiency difference if only use 2.5V and 1.1V

Is only 489.38mW-453.94mW difference?

2. If only use 2.5V and 1.1V will have any side effect except the efficiency? (like stability)

3. The KSZ9031RNX pin43  can control MOS to transfer 3.3V to 1.1V. Is TI phy also have this function?

    Hi Kevin,

    To answer your questions:

    1. Yes, this information is correct.

    2. There are no side effects of using dual versus triple supply configuration, but efficiency is different. Two supply configuration uses an internal regulator to supply 1.1V. Three supply configuration uses external regulator. 

    3. The TI PHY does not have this function.

    Thank you,

    Nikhil
