Hi ti team，

Replacing DP83848KSQ/NOPB with DP83848CVV/NOPB, is the software debugging the same?

Hello,

Thank you for your response. Please note the US offices are closed for Thanksgiving Holiday and will look to reopen next week.

Sincerely,

Gerome

Hello,

It would be best to go through each device's datasheet to understand the key differences. One of the first things to note between the -K and -C is a difference is PHY ID (Reg 0x3).

Sincerely,

Gerome

Hi Gerome，

25-MHz Crystal Specification: The minimum capacitance is 25PF, but the reference design is 18PF, what is this?

Datasheet：

reference design：

Hi,

For xtal guidance, please check in with xtal vendor for appropriate load capacitor value for component and PHY.

In addition, the load cap is actually 36pF in the reference design.

Sincerely,

Gerome

Hi Gerome，

What is the minimum capacitance?

Hi Gerome，

Please check if the cap below is suitable.

Hello,

It is best to check with the xtal vendor for this as it is strongly dependent on the xtal. I noticed for this xtal that the load cap typical is 8pF, while the theoretical load cap would be 24pF.

Sincerely,

Gerome
