Method and circuit arrangement for calibration of a sampling control signal which influences the sampling time of a received signal from a sampling phase selection element

摘要

A discrete sampling control signal, which influences the sampling time, from a sampling phase selection element is calibrated by definition of quantization intervals for a sampling time error signal. For this purpose, a received signal is shifted through a series of time shifts τ_i in the signal path upstream of the sampling phase selection element. The sampling time errors e_i associated with the respective time shifts τ_i are measured. The quantization steps of the sampling control signal that are suitable for the sampling phase selection element are then determined from the relationship obtained between τ_i and e_i.
