ABSTRACT:
A digital communication system for transmitting and receiving Digital Visual Interface (DVI) communication data signals and Display Data Channel (DDC) communication signals over a transmission line comprises an open-loop equalizer circuit and a DDC extension circuit. The open-loop equalizer circuit is operable to receive DVI communication signals transmitted over the transmission line and output equalized DVI communication data signals. The DDC extension circuit is operable to inject a boost current at the receive end of the transmission line during a positive transition in the DDC communication signal, and clamp the receive end of the transmission line during a negative transition of the DDC communication signal.
