Hi, i have done a short search on special AC coupling capacitors for serial interfaces (PCIe, SATA, .. ) , but found nothing really special. I have found Steves DesignCon 2012 presentation, but this deals more with characterization than performance requirements. Is there something better available, than a standard C0G/X7R capacitors ?
