    摘要: A digital fractional phase detector is shown that uses a phase error detector for generating a phase error signal based on the phase difference between a reference clock signal and a feedback clock signal. A quantizer directly measures the pulse width of a phase error signal and outputs the value in a digital form. By directly measuring the phase error signal, quantization accuracy is increased. In order to calibrate the digital fractional phase detector, a calibration pulse generator generates a calibration pulse of a known duration and passes it to the quantizer.

    摘要: A method for adjusting parameters of an adaptive equalizer makes use of a transmitted signal received by a receiving end to adjust parameters of an adaptive equalizer. First, signal strengths of a first frequency band and a second frequency band in the transmitted signal are detected. The signal strengths of the first frequency band and the second frequency band are then compared to get a compensation ratio, i.e., the total compensation quantity of the first frequency band to the second frequency band. Finally, the parameter setting of the equalizer is adjusted according to feedback of the compensation ratio. Optimum gain control of the adaptive equalizer can thus be accomplished to compensate signal attenuation to the transmitted signal caused by the channel.
