Part Number: DP83848K

Dear support team

I'm going to make prototype with DP83848.

And I have two question. Please give advice about it.

(1) I select SG210STF(Oscillator) and SL-60182-F(RJ45 connector).

From view of spec these part can use? (Could you check?)

(2) How much current can LED_LINK and LED_SPEED pin supply?

<SG-210STF>

<SI-60182-F>

Hello Geet-san

Thank you for quick response.

Pk to Pk Jitter of sister product (48MHz) is typ 20ps

So, jitter spec may meet the DP83848.

Does it seems that there is no problem other that?
