  • Patent number: 8555103
    Abstract: A deskewing apparatus includes a power supply connector, a oscillator, a first switch unit, a second switch unit, a first logic member, a second logic member, a clock generator and a plurality of output channels. The oscillator generates an electrical signal with a predetermined frequency and sinusoidal waveform. The first switch unit and the second switch unit each generates on/off signals by controlling power on/off. The first logic member and the second logic member generate logic signals according to the corresponding on/off signals from the first switch unit and the second switch unit. The clock generator multiplies the frequency of the electrical signal based on the combination of the logic signals and converting the electrical signal from sinusoidal waveform into rectangular waveform. The output channels output the converted electrical signal.
