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

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 -
