DP83561-SP: PHY sequencing

Tijana Igic1
Prodigy 150 points

Part Number: DP83561-SP


What behavior could we expect from the part if this power sequence is not followed, either with longer delays or a different order? Is there any risk of damage to the part?

    Hi Tijana,

    The main concern with an incorrect power sequencing is potential functional problems with the PHY. A power-up sequence that does not follow the datasheet guidelines could result in improper internal initialization or latch-up. If the power supply magnitudes are within the min/max specs listed in the datasheet, permanent damage to the part is not likely.

    Best regards,

    Greg
