ABSTRACT:
A transmission line driving circuit that can support a high-rate signal transmission and further can perform appropriate loss compensation in accordance with a signal pattern. A transmission line driving circuit1comprises a plurality of driver input circuits20that serve as signal analyzing unit for analyzing the content of the signal pattern of an input signal; a plurality of lowpass filters30; a plurality of gain adjusting circuits40; a plurality of adders50; and adder52; and a driver output circuit60that outputs, in accordance with a signal analysis result, a signal the phase of which has been adjusted in such a direction that cancels the timing deviation caused by a loss occurring when the input signal is transmitted to the transmission path. The output signal from the driver output circuit60is transmitted to the transmission path2.
