Claim 0:
1. Time-to-digital converter (TDC) circuitry for converting a phase difference between an input reference signal and an input clock signal to a digitally represented output signal, the TDC circuitry comprising:
a plurality of constituent TDCs, wherein each constituent TDC is configured to convert a phase difference between a constituent reference signal and a constituent clock signal to a digitally represented constituent output signal;
a reference signal provider configured to provide the respective constituent reference signals to each of the constituent TDCs, wherein—in at least a parallel operation mode of the TDC circuitry—each respective constituent reference signal comprises a respectively delayed version of the input reference signal with different respective delays for at least two of the respective constituent reference signals; and
a digital signal combiner configured to provide the digitally represented output signal based on the digitally represented constituent output signals of the constituent TDCs.
