The interface circuit has two driver circuits and a drive control circuit that can switch between two driving systems that are a voltage driving system and a current driving system. The two driver circuits are connected to a power supply potential via the drive control circuit. Two input signals and inverted logic signals of the input signals are inputted via a selection circuit. According to a control signal inputted into the drive control circuit, the interface circuit switches between the voltage-driving type single-ended transmission system and current driving type differential transmission system.

摘要： The logic block 103 generates a serial-data signal DATA using a clock signal CLK generated by a clock generator 104. Then, a skew adjusting unit 111 adjusts a delay of the serial-data signal DATA based on the phase relationship between the clock signal CLK and the serial-data signal DATA, and outputs resultant serial-data signal DATA-SK and clock signal CLK to a FF circuit 112. The FF circuit 112 shapes the serial-data signal DATA-SK using the clock signal CLK, and transmits the resultant serial-data signal DATA-FF to outside the device. Accordingly, even if jitter of a clock signal is superimposed on a data signal after signal processing, the influence of this jitter is reduced, thus providing a data transmitting device capable of transmitting a data signal to outside the device with the influence of the jitter reduced.
摘要翻译：逻辑块103使用由时钟发生器104产生的时钟信号CLK来产生串行数据信号DATA。然后，偏斜调整单元111基于时钟信号CLK的相位关系来调整串行数据信号DATA的延迟和串行数据信号DATA，并将合成的串行数据信号DATA-SK和时钟信号CLK输出到FF电路112.FF电路112使用时钟信号CLK对串行数据信号DATA-SK进行整形，并发送得到串行数据信号DATA-FF到设备外部。因此，即使信号处理后的时钟信号的抖动叠加在数据信号上，也能够减轻抖动的影响，提供能够以抖动减小的方式将数据信号发送到设备外部的数据发送装置。
