摘要： A transmission unit sequentially outputs a plurality of data signals in a predetermined transmission period during which a one-frame image is transmitted, the predetermined transmission period being defined by a product of a number of the given units and a transmission period of a given unit. Meanwhile, the transmission unit outputs a control signal in the period among the predetermined transmission period that is equivalent to a sum of the transmission time of the given units which does not include the data signals. This period corresponds to the sleep mode period of the transmission unit. The sleep mode period is set such that a ratio of the sleep mode period to the predetermined transmission period is larger than a ratio of a sum of a transmission period of the control signal and a margin period for transmission of the control signal to the predetermined transmission period.

摘要： A data transmission system is provided with a transmission unit, a receiving unit, transmission paths, and a delay unit. The delay unit is disposed on a transmission path along which a high-speed signal is transmitted, and delays the transmission of the high-speed signal with respect to a low-speed signal. When the high-speed signal is transmitted from a section b2 to c along the transmission path, a delay time of Δt occurs with respect to when the high-speed signal is transmitted from a section a to b1 along the transmission path. In other words, the phase of the high-speed signal transmitted from section b2 to c is shifted with respect to the phase of the high-speed signal transmitted from section a to b1. Consequently, a time interval in which an EMI peak value occurs can be reduced, thereby enabling the probability of an EMI peak value occurring to be reduced.

摘要： A semiconductor laser drive apparatus comprises a bias current setting section (232) which sets a bias current value on the basis of the drive temperature so that the temperature characteristic of the bias current value with respect to the drive temperature may be a linear function having a slope except zero and a drive current setting section (233) for setting the drive current value on the basis of the drive temperature so that the temperature characteristic of the drive current value with respect to the drive temperature may be a function having a slope except zero. The temperature characteristic of the bias current and that of the drive current are functions different from each other. With this, low cost, space-saving, and power-saving of a semiconductor laser are achieved, and a semiconductor laser drive apparatus enabling a good transmission characteristic on the reception side and a high optical output over the whole drive temperature range when driving the semiconductor laser can be provided.
