Apparatus and method to recover a data signal

Embodiments of the present invention disclose an apparatus and method for recovering a data signal in a digital transmission. A computer processor receives a data signal from a data signal input wire. The computer processor receives an external clock signal. The computer processor samples a binary bit of the data signal multiple times per clock cycle. The computer processor determines, for each sampling group, a sample and a quality measurement. The computer processor stores, for each sampling group, the sample and the quality measurement into a set of memory elements. The computer processor stores the sample from each sampling group into a first and a second delay chain. The computer processor determines a current sampling point. The computer processor transmits output corresponding to a content of the current sampling point to a data signal output wire.
