An HDMI cable may exhibit frequency dependent signal attenuation, inter symbol interference, and inter-pair skew. A boost device integrated with the cable can compensate for such impairments of the cable. A self calibrating cable with a boost device of the embodiment of the invention is described, in which parameters that control the response of the boost device are set optimally in a self-calibrating process comprising looping the boosted cable on itself through a calibration fixture that contains a calibration control device. The boost device includes pattern generators and a sampling circuit. Each high speed channel of the cable is separately tested and calibrated with the help of one of the other channels serving as a sampling channel.
A method for calibrating a high speed cable having a boost device embedded in the cable, the cable carrying a plurality of high speed channels and a low speed control bus, the cable including an input connector and an output connector, the method comprising:
A system for calibrating a high speed cable, carrying a plurality of high speed channels and a low speed control bus, the cable having an input connector and an output connector, the system comprising:
A self-calibrating high speed cable, carrying a plurality of high speed channels and a low speed control bus, the cable having an input connector and an output connector, the cable comprising:
