Patent ID: 8108710

Claim:
A high speed communication link comprising: a transmitter generating a differential signal having a positive and a complementary negative component; a pair of transmission lines wherein each of the positive and negative components of the differential signal are transmitted over a respective one of the pair of transmission lines; a terminator for reducing reflections of the differential signal; a skew compensation circuit receiving the differential signal, the circuit including: a skew detector for determining the skew between the positive and negative components of the differential signal; a plurality of delay elements, wherein each of the positive and negative component of the differential signal are transmitted through a respective delay element; and a controller, wherein upon receiving an input signal from the skew detector, generates an output compensation signal for each of the positive and negative components of the differential signal; wherein the skew compensation circuit is disposed between the terminator and the receiver, and measures skew between the positive and negative components of the differential signal and adaptively compensates for the skew; and a receiver receiving the differential signal.
