ABSTRACT:
A high-speed digital interface circuit for use with an N bit digital data signal is disclosed. The circuit comprises a source device that initially receives the N bit digital data signal, and a sink device that receives the N bit digital data signal from the source device. The N bit digital data signal has a skew when received by the sink device. A skew detection circuit in the sink device detects the skew in the N bit digital data signal and generates a skew detection signal. A line supplies the skew detection signal to the source device. A compensation circuit in the source device receives the skew detection signal and compensates for the skew in the N bit digital data signal.
