Abstract
A digital data signal capture circuit for synchronization of received digital data signals includes a transition detector for determining a state transition of the received digital data signal. The transition detector samples the received digital data signal at a first time, a second time and a third time and determines whether the transition occurs between the first time and the second time and whether it occurs between the first time and third time and generates an increment/decrement signal indicating a position for the transition. A strobe adjust circuit generates a strobe signal based on the increment/decrement signal. A capture circuit captures the received digital data signal using the strobe signal.
