This application note gives PCB design tips for reducing EMI in automotive environments. A lot of the advise can be applied to any PCB layout.
Electromagnetic interference (EMI) and electromagnetic compatibility (EMC) testing is an important part of design verification for serializer/deserializer (SerDes) devices in automotive applications. EMI and EMC must be considered early in the design cycle to prevent needless design revisions. The following application note details helpful, basic concepts and guidelines on how to prepare your SerDes system for EMI/EMC testing.
