Problems solved by technology

[0003] However, when the transmission speed is required to be around gigahertz, there is a limit to responding only with equal-length wiring, etc.
In addition, it is difficult to achieve stable high-speed transmission due to the influence of noise or jitter (fluctuation in the delay time of data signals), etc.

Abstract

A data transfer device includes: a reception unit which receives a reference signal and a data signal of transferred data; a holding unit which holds a test signal of test data received prior to the data and the reference signal; a calculation unit which calculates a delay amount of the data signal and the reference signal generated until reception by using the test signal and the reference signal held in the holding unit; and a delay unit which relatively delays the data signal against the reference signal in accordance with the delay amount.

Description

technical field [0001] The invention relates to a data transmission device suitable for high-speed transmission of digital data between electronic equipment or between semiconductor elements and its peripheral technology. Background technique [0002] In recent years, high-speed digital data transmission has been demanded along with the increase in the number of pixels of imaging elements. Conventionally, in the design of electronic equipment for high-speed transmission, the impedance control of the transmission line, the selection of materials such as equal-length wiring and printed circuit boards, and the simulation of signal waveforms were further performed. [0003] However, when the transmission speed is required to be around gigahertz, there is a limit to responding only with equal-length wiring. Furthermore, due to the influence of noise or jitter (fluctuation in delay time of data signals), etc., it is difficult to realize stable high-speed transmission. Therefore,...
