Abstract
A phase of a sampling clock provided from clock generating circuitis switched periodically and alternately with a phase difference of 180 degrees, and during a period of each phase, timing estimating circuitestimates a symbol timing. High-accuracy timing estimating circuitselects an estimated result with higher reliability among symbol timing estimated results obtained in respective periods, thereby enabling estimation of the symbol timing with time resolution twice a sampling period. It is possible to decrease an operation frequency in an A/D conversion circuit even in a system requiring timing synchronization accuracy with high accuracy.
