| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Purpose of this study is discussed about degradation of the signal transmission and influence of impedance variation on the USB Type-C connecter. In this paper, printed circuit board (PCB) mounted the USB Type-C connecter model is created by 3D CAD(Fusion360), and transmission characteristics on the USB Type-A and Type-C connecters are calculated by FDTD implemented the 3D model. From transmission and reflected characteristics of the mixed-mode S parameter, transmission characteristic is larger than -7 dB at less than 1.7 GHz for Type-A connecter and less than 25GHz for Type-C connecter. For the TX± and D± of Type-C connecters, Scd11 for the TX± located on the side of connecter is larger about 20 dB than that of the D±. To discuss the variation of signal construction on the connecter, the impedance calculated by TDR changes on the connection part between connecter and PCB. It is possible to course of degradation of signal integrity and increased of EMI. | |
