Abstract:
1. An apparatus for transmitting a digital visual interface (DVI) signal, comprising: a differential driver; a differential receiver; one or more transformers, each of the one or more transformers connected to the differential driver and differential receiver; and at least one cable equalizer interposed between one of the one or more transformers and the differential receiver; wherein: the cable equalizer circuit is configured to recover high frequency components of at least one of the one or more balanced DVI signals; the differential driver is configured to receive one or more ground-up DVI signals; the differential driver is configured to convert the one or more ground-up DVI signals into one or more balanced signals, each comprising two waveforms of substantially similar magnitude but opposite voltage with reference to a ground; the one or more transformers are configured to receive the two waveforms and transmit the two waveforms to a DVI compliant cable; and the differential driver and one or more transformers are configured to remove all direct current signals before transmitting the two waveforms via the DVI compliant cable.
