Abstract
A cable device includes an integrated surge protection circuit. In the event that, communication signals conveyed by the cable include (potentially damaging) transient voltages, the surge protection circuit integrated in the cable suppresses the transient voltages at a distance from a corresponding electronic circuit to which the cable is attached. Consequently, potentially damaging voltage transients imparted on the communication signals are clamped before reaching potentially sensitive inputs of the electronic circuit.
