A symbol timing recovery detector receives a sample stream, representing an input signal having successive symbol times sampled at successive sample times. The sample stream includes samples representing successive symbols alternating with samples representing transitions between surrounding symbol representative samples. The detector includes a first circuit which determines a transition value from a transition representative sample and surrounding symbol representative samples. A second circuit determines the slope between the surrounding symbol representative samples. A third circuit generates a signal representing the phase error between the sample times and the symbol times of the input signal from the slope and the transition value.
