ABSTRACT:
A receiving equipment comprises a modulator, a timing extraction unit, a PLL unit, an impulse recovery unit, a fix-equalizer, and an automatic-equalizer. A timing pull-in operation is performed, in one way, by phase-rotating a timing signal of the timing extraction unit and sends the signal to the PLL unit, and in another way, by introducing an input signal of the timing extraction unit from the equalized output of the fix-equalizer.
