Abstract
A method for processing a received digital signal includes generating a clock signal used for sampling the received signal by comparator which compares the received signal to a reference. A phase shifter adjusts the phase of the first clock signal to maximize the vertical eye opening of the signal at the sampling time. The phase of the clock signal may be adjusted in a first direction and a measure of vertical eye opening of the signal compared to a previous measure. If the measure of vertical eye opening has increased the signal another phase adjustment may be made in the same direction whereas if the vertical eye opening of the signal has decreased a further phase adjustment in the opposite direction may be made.
