Figure A￿14: Output Waveform

If a cable is used, these waveforms have transmission distortion. It is necessary to latch the data with a clock before using the waveform in actual circuits at the cable receiving side (user side) and to reproduce the waveform. Delay the clock with the delay line in order to reproduce the data reliably (see Figure A-15).
