摘要： A method to assess signal transmission quality and the adjust method thereof are proposed. First, different time points of a control signal at a receiving end are acquired and the number of signal transitions in a predetermined time interval is counted. Next, the number of signal transitions is recorded and compared to a reference value to obtain a comparison result. The quality of the control signal is then determined based on the comparison result. The parameter setting of the receiving end is adjusted according to the quality of the control signal received by the receiving end to get a better performance setting.

摘要： A phase frequency detector used in a phase locked loop includes a phase error detecting unit for outputting phase error signals according to a phase error between a first input signal and a second input signal, and a reset unit coupled to the phase error detecting unit. The reset unit outputs reset signals according to the first and second input signals so as to reset the phase error detecting unit without delay time. Thus, it is possible to make the output timing of the phase error signal in a more precisely linear proportion to the phase error value and to enhance the sensitivity of the phase locked loop.
