Abstract: A system may include a first stage comprising first signaling components for a first protocol, and a second stage comprising second signaling components for the first protocol and a second protocol. The system may further include logic configured to receive an incoming data stream, and determine a stream protocol for the data stream. The logic may be further configured to, responsive to the determination, activate the at least a portion of the first stage when the stream protocol is compliant with the first protocol, and when the stream protocol is compliant with the second protocol, deactivate the first stage.

Abstract: A device for digitally protecting against an overvoltage event may include a front-end circuit, an overvoltage protection circuit, and a protection switch. The protection switch may be coupled to the overvoltage protection circuit and may be configured to decouple the front-end circuit from an external medium, in response to a clamp signal. The overvoltage protection circuit may be configured to detect the overvoltage event at one or more nodes of a circuit. In response to the detection of the overvoltage event, the overvoltage protection circuit may generate the clamp signal to activate the protection switch.
