Kind Code:
A1
Abstract:
The present disclosure relates to a receiver and to a method implemented in the receiver for recovering a signal clock from a received data signal. Successive edge transitions between successive data samples of the received data signal are detected according to a clock recovered in the receiver. The recovered clock is adjusted based on a combination of weights assigned to at least some edge transitions among the plurality of successive edge transitions. In particular, (i) each very early transition is assigned a first weight having a first sign, (ii) each early transition is assigned a second weight having the first sign, (iii) each late transition is assigned a third weight having a second sign opposite from the first sign, and (iv) each very late transition is assigned a fourth weight having the second sign.
