A method for recovering a clock signal from a data signal by using a clock recovery module is described. Edge timings of the data signal are accumulated. The edge timings accumulated are transformed into one reference bit period. A time offset for the reference bit period is determined. A reference clock signal is determined based on the time offset. The number of bits within a system clock of the clock recovery module is determined. The clock signal is recovered based on the reference clock signal and the number of bits. Further, a clock recovery module as well as a computer program are described. 1. A method for recovering a clock signal from a data signal by using a clock recovery module , with the following steps:accumulating edge timings of the data signal,transforming the edge timings accumulated into one reference bit period,determining a time offset for the reference bit period,determining a reference clock signal based on the time offset,determining the number of bits within a system clock of the clock recovery module, andrecovering the clock signal based on the reference clock signal and the number of bits.2. The method according to claim 1 , wherein the clock signal is recovered by an interpolation on the reference clock signal and the number of bits.3. The method according to claim 1 , wherein another clock signal is estimated based on the edge timings.4. The method according to claim 1 , wherein a bit period is estimated.5. The method according to claim 1 , wherein several system clocks are summarized to a virtual system clock claim 1 , and wherein the virtual system clock is de-virtualized afterwards.6. The method according to claim 5 , wherein the edge timings in the virtual system clock are normalized claim 5 , and wherein the normalized edge timings are de-virtualized after the clock signal is recovered.7. The method according to claim 1 , wherein the value of the time offset determined is corrected to obtain a corrected time offset claim 1 , and ...
