Hi,
As far as I know, you have to use ferrite bead.
Because the inductor(FB2) was used “HB-1M1608-121” in the W5100E01- AVR schematic.
Please refer to as below.

thanks,

Hi,
What is exact value of inductor FB2 in this circuit ? ( as you mentioned its part no. is “HB-1M1608-121” )
I saw in the schematic that the digital ground ( GNDD ) and analog ground ( GNDA ) pins of the chip is tied together. Is it right ? I must short these pins ?
Regards.

Hi,
You have to use 0.5A or 0.3A/120 ohm or 60 ohm as Ferrite bead value and we use the “HB-1M1608-121”.
I recommend that these pins(GNDD/GNDA)is connected to Ferrite bead for stability.
thanks,
