Summary:The present invention provides a timing adjustment circuit and method. The circuit includes a second timing adjustment unit, a multi-staged sampling circuit and a determination circuit for adjusting the receiving timing of an output signal transmitted by a first chip and received by a second chip. The method includes using the multi-staged sampling circuit to receive a receiver clock signal and generate a plurality of sampling clock signals; then, sampling the output signal based on the sampling clock signals to generate a plurality of sampling signals; and finally using the determination circuit to compare the sampling signals based on the output signal so as to generate a second adjustment signal for being transmitted to the second timing adjustment unit for adjusting the phase of a basic clock, and generate and adjust the clock signal of the receiver for adjusting the receiving timing of the output signal received by the second chip. In addition, the determination circuit also transmits a first adjustment
