Hello,

Regarding to LED Interface and internal PU/PD on DP83848K, my customer has some question.

(Question)

(1) How many currents are sink/source maximin current of LED interface(LED_SPEED/LINK)?

(2) How many resistors are internal PU/PD resistor?

We couldn’t find out them on datasheet.

Hi Tao,

Because this is an older part, we do not have the ability to simulate the current sink/source information. This info can be found by testing. If you would like me to test it, the earliest I could probably test this information would be at the beginning or middle of next week.

Please let me know how you would like to move forward.

Also, could you please clarify your second question?

Thanks,
Lysny
