Abstract
A method and apparatus is disclosed that includes first and second hardware components. The first component includes at least one first input configured to receive at least one first data or power signal, at least one voltage clamping circuit configured to limit a voltage of the at least one first data or power signal, and at least one first output configured to provide the at least one voltage-limited first data or power signal. The second component includes at least one second input configured to receive at least one second data or power signal, at least one limiter circuit configured to limit an amount of energy in the at least one second data or power signal, and at least one second output configured to provide the at least one energy-limited second data or power signal.
