A signal deskew circuit is provided, which includes first and second signal branches, each branch extending between a start location and a respective end location. Each signal branch includes a send path and a return path, which have substantially the same propagation delays. An adjustable delay buffer is coupled in the send and return paths of a first of the signal branches and has a delay, which is adjustable based on a respective adjust signal. A skew sensor coupled to the return paths of the first and second signal branches, which generates the respective adjust signal for the adjustable delay buffer based on a phase difference between signals on the return paths of the first and second signal branches.
