Abstract
Methods, integrated circuits and computer-readable media for communicating back-channel data over a data link by modulating the phase or frequency of a clock signal of a data signal transmitted over the data link. Slow modulation of the clock signal allows it to be detected and extracted by a receiver without affecting the integrity or bit rate of the data signal. Some embodiments allow the functionality to be implemented without the use of extra hardware in the transmitter or receiver or either.
