Abstract
A multi-channel receiver, digital edge tuning circuit and a method for operating the same is disclosed. The digital edge tuning circuit for tuning phases of an input signal and a clock signal, comprises a delay-tuning circuit for receiving the input signal and delaying the input signal to generate a fine-tuned signal; a delay set comprising a plurality of delays connected serially one by one, the input of the delay set coupled to the fine-tune circuit, for receiving the fine-tuned signal; a plurality of sample/hold circuits, each of the sample/hold circuits coupled to a corresponding output of one of the delays and the fine-tune circuit, for sampling and holding the corresponding output; and a dynamic edge tuning circuit, coupled to the sample/hold circuits, for controlling a common delay time delayed by the delay-tuning circuit according to which one of the sample/hold circuits samples a data edge of the input signal.
