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 circuitcomprises a plurality of driver input circuitsthat serve as signal analyzing unit for analyzing the content of the signal pattern of an input signal; a plurality of lowpass filters; a plurality of gain adjusting circuits; a plurality of adders; and adder; and a driver output circuitthat 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 circuitis transmitted to the transmission path
