A data capturing device is provided. The data capturing device includes a data capturing device controller and data capturing components. The data capturing device is arranged to send a burst read command. Each of the data capturing components includes a DLL component, a data sampling component, a comparison component, and a valid clock calculation component. The DLL component is arranged to provide clock signals. The data sampling component is arranged to receive a serial data signal that includes a read preamble, where the read preamble includes a training pattern, and to sample the serial data signal with each of the clock signals. The comparison component is arranged to compare each of the sampled data signals with an expected training pattern. The valid clock calculation component is arranged to, based on the comparisons, select one of the clock signals as the valid clock signal for locking the DLL component to. |
