Patent 10425161 was granted and assigned to Silicon Line GmbH on September, 2019 by the United States Patent and Trademark Office.
Enabling Low Frequency Periodic Signalling over an optical link with a circuit arrangement and method for controlling a light-emitting component, including: monitoring a differential input for the presence of an electrical idle state by an IDLE detector; triggering a time delay block by the IDLE detector when the electrical idle state at the differential input is interrupted or resumed; detecting whether the differential input is driven by a Low Frequency Periodic Signalling or by a Super Speed/Enhanced Super Speed signalling by a signal type detector; making a decision whether the signalling is to be transmitted by a decision circuit; an input stage connected to the decision circuit; and driving the light-emitting component by an output stage.
