SELF CALIBRATING CABLE FOR A HIGH DEFINITION DIGITAL VIDEO INTERFACE
摘要
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 is described in which parameters that control the response of the boost device are set optimally in a self-calibrating process consisting of 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.
