DATA SIGNAL SAMPLING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a data signal sampler for exactly sampling data of data signals to be serially transmitted, even if a phase deviation or the like occurs.

SOLUTION: A phase deviation quantity calculator circuit 13 calculates an out-of-phase quantity S13. A correction quantity calculator circuit 14 calculates a correction quantity S14 from the value of the out-of-phase quantity S13. A sampling interval corrector circuit 10 corrects a sampling interval value S9 according to the correction quantity. A sampling pulse generator circuit 11 generates a sampling pulse S11 from the sampling interval correction value S10, thereby sampling data from converted binary signals S8 based thereon.
