AMC1303M2520: Radiated emission measurement for products using AMC1303

Guru 10050 points
Part Number: AMC1303M2520

Tool/software:

Hi,

Q1.
When measuring radiated emission for products using AMC1303, the noise emitted from this IC is large, so I would like some advice on noise reduction measures.

Q2.
I am considering the following two points.
 -Adding ferrite beads to the power line
 -Adding an RC filter (100Ω, 33pF) to the output (MCLK, MDAT)

Regarding adding ferrite beads to the power line, is it recommended to put this ferrite bead between the IC and the 0.1uF ceramic capacitor (in the order IC-ferrite beads-0.1uF-2.2uF-VCC)? Or is it recommended to put it between the VCC and the 2.2uF ceramic capacitor (in the order IC-0.1uF-2.2uF-ferrite beads-VCC)?

Thanks,

Conor
