Abstract:
In one aspect, an apparatus includes: a first time-to-data converter (TDC) to oversample a first duration of incoming data and hold the oversampled first duration during receipt of a second duration of the incoming data; a second TDC to oversample the second duration of the incoming data and hold the oversampled second duration during receipt of a third duration of the incoming data; a processing circuit coupled to the first and second TDCs, the processing circuit including a first filter to filter the oversampled first duration and the oversampled second duration and generate a control output therefrom; and a digitally controlled oscillator (DCO) coupled to the processing circuit to receive the control output and generate a recovery clock signal therefrom.
