Abstract
A system to protect signal integrity includes a circuit board having a secure portion and a non-secure portion. The secure portion includes a protected circuit operable for storing security relevant data, and a secure portion power-supply element. The non-secure portion includes an unprotected circuit and a non-secure portion power-supply element corresponding to the secure portion power-supply element. The secure portion and the non-secure portion element are separated by an isolation gap. A coupling element bridges the isolation gap between the secure portion and the non-secure portion. The coupling element is electrically connected to the secure portion power-supply element within the secure portion and electrically connected to the non-secure portion power-supply portion.
