摘要： 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.

The complex switch section supplies the selection potential produced using the first scan electrode group drive section to the second scan electrode group drive section for driving the second scan electrode group in the latter half of the scan period. The second scan electrode group drive section supplies scan pulses based on the input selection potential.
