Actually, my question was about Flat panel driver ICs, particularly about chips
Intersil Techwell TW8804 and National Semiconductor DS90C385A. I had hope that
somebody has valuable experience with this problem. Thank you anyway,Eugene

general recommendations also say to reduce common mode current. But obviously
this shouldn't have been said too:)

It seems to me that claiming familiarity with general recommendations severely
restricts what anyone can add. The general recommendation for reducing RE is to
minimise the areas of current loops by pairing 'go' and 'return' conductors on
adjacent layers of the PC board. But you obviously know that already. With best

Subject: [PSES] RE from Flat PanelICs Dear experts,Flat panel driver ICs are
known for their high emission. I have some problems with radiated emissions
particularly from chips Intersil Techwell TW8804 and National Semiconductor
DS90C385A.Could you, please share your knowledge about reducing this RE. We are
familiar with generalrecommendations. Thank you,Eugene -
