DP83822H: LED_x and VDD/AVD voltage

Yuto Kitamura
Expert 6725 points
Part Number: DP83822H


Tool/software:

Dear team,

Let me confirm 2points to use DP83822HRHBR.

1. Can we use it with VDDIO=1.8V and AVD=3.3V?

2. As shown in datasheet, can we use LED_0 and LED_1 with both source and sink configuration?
Also can I know the current drive capability of these pins?

Thank you,
Yuto Kitamura

    Hello,

    1) This configuration look okay.

    2) LED_0 and _1 should be okay to use in this configuration. Per DC specs, looks like the pin can drive atleast 4mA. For good rule of thumb, if customer follows configuration per datasheet, everything should be fine regarding functionality/strapping.

    Sincerely,

    Gerome
