LMK03318: Power Supply for LMK03318

Part Number: LMK03318

Hi

My question is regarding the power supplies which power the PLL.

Usually, I provide PLL power pins from LDO.

But:  The LMK03318 has internal LDO’s (according to section 10.3.1).

From the data sheet the accuracy of the external power supplies is +-5%.

Can I power the PLL from DC2DC - due to the fact it has the internal LDO's?

If so, is there any specific guidelines for the DC2DC?

Required RFI filters and so on?

Regards

Omer
