Abstract
The invention provides a method for recovering a digital datastream, in which a reference clock phase is recovered from the digital datastream, the digital datastream being received in a datastream receiver, low-pass filtered in a low-pass filter device, an edge position signal being determined by comparing an amplitude of the low-pass filtered datastream with a predetermined threshold value in an edge position detection device and a phase deviation being determined from a time difference between a 0/1 threshold intersection point of the threshold value with a 0/1 data transition or a −1/1 threshold intersection point of the threshold value with a −1/1 data transmission and the target time of the control system in a phase correction device, so that the phase deviation can be corrected with the phase correction offset in the phase correction device.
