In one embodiment, a method includes receiving a data signal comprising a plurality of bits. The method further includes generating a clock signal. A plurality of samples is acquired from the data signal at a sampling rate determined by the clock signal and it is determined whether a transition point from a first bit in the plurality of bits to a second bit in the plurality of bits occurs within the plurality of samples. If it is determined that the transition point occurs within the plurality of samples, a state machine comprising a plurality of states transitions from a first state to a second state. If the second state indicates a non-zero amount of phase displacement between the clock signal and the data signal, the clock signal is adjusted to correlate with the data signal.
