    Reducing EMC on CCA - Strategies and Suggestions

    Ok, let me add further details.. We have 24MHz and 27MHz crystals in the design, they both have 33 ohm series resistors at the output. The crystals are as close to the IC as possible. Our product is audio and video based... We have RE violations up to the 7th harmonic of these base frequencies...

    Reducing EMC on CCA - Strategies and Suggestions

    I do not intend to be overly vague... It should actually be a simple answer...I could take a snapshot of the schematic to show the inductors in series with the power pours... I have not located anything on the web to indicate the inductors reduce the high frequency noise.. I believe they are...

    Reducing EMC on CCA - Strategies and Suggestions

    yes this is a PCB which has been built...Yes we have a ferrite bead on the digital and analog ground plane. I just do not believe adding ferrite beads on Digital power pours is helping us...

    Reducing EMC on CCA - Strategies and Suggestions

    We have a design which has some radiated emissions exceeding are stated levels. We are trying to reduce our emissions profile. 1) We have increased our series termination resistors to "soften" the clock edges 2) I am looking at the various added inductors added to the power pours and...
