Esteemed Colleages; Has anyone had experience using Audio-Codec '97 (AC 97) topology with respect to EMC performance. It is commonly used in PC sound cards. We have a device that incorporates this technology for voice recognition and are seeing very high emissions between 100-600 MHz. The offending RF noise source appears to be entirely differential.
