Looking at the schematic of the evaluation board they recommend 15uH + 680nF when using the M version, but when the L version is used the L is a ferriet (NFZ2MSM181SN10L) and the C is 330pF. I can't find no explanation about the output filter.
Off course I can do what is told, but I try to understand why. Why is a ferriet used instead of the 15uH and what is best?
For the NFZ2MSM181SN10L a can't find an graph, but if it is 180 ohm @100MHz, it seems to me that it doesn't filter a lot on 48kHz.
