PRODUCTION DATA.
For high-frequency signals going to connectors choose a fully shielded connector, if possible (for example, SD card connectors). For signals going to external connectors or which are routed over long distances, it is recommended to reduce their bandwidth by using low-pass filters (resistor, capacitor (RC) combinations or lossy ferrite inductors). These filters will help to prevent emissions from the board and can also improve the immunity from external disturbances.
