Patent attributes
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 circuit 1 comprises a plurality of driver input circuits 20 that serve as signal analyzing unit for analyzing the content of the signal pattern of an input signal; a plurality of lowpass filters 30; a plurality of gain adjusting circuits 40; a plurality of adders 50; and adder 52; and a driver output circuit 60 that 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 circuit 60 is transmitted to the transmission path 2.
