DP83TG720R-Q1: LED_0, LED_1 strap configuration

Part Number: DP83TG720R-Q1


Hi!

Can you please confirm strap configuration for pins LED_0 and LED_1 while using the LED functionalities. For example, we would like to use MS=Slave and AUTO=Autonomous. By the following table those two options are both MODE 1.

By this table, MODE 1 means to leave the pin floating:

I if understood correctly, if we are using LEDs and we want MODE 1 (open, float) we would need to put additionally pull-down resistors as in the following image, right?

Best regards,

Matej

    Hello,

    Thank you for your query. The US offices are closed for July 4th. As such, I will relay this information to the team and look to get feedback around the middle of the week.

    Sincerely,
    Gerome

    Hello,

    As all bootstrap pins are internal PD, Rp can be omitted in this specific instance as the voltage at that pin would be dictated by the internal PD. However for other products, it is important to discern if the pin is a internal PU or PD, as if you would like to utilize the same circuit with a PU internal pin (if one were to exist in another PHY we offer), that is where Rp will be needed.

    Sincerely,

    Gerome
