Design and verification of a high-speed connector for multi-media system

Recently, the number of high-definition media devices such as 8K ultra high-definition (UHD) TV and virtual reality (VR) is rapidly increasing. These multimedia systems require higher data rates for high resolution and versatility. With this increasing technical trend, high-speed connectors and cables are also becoming important. In this paper, we propose a highspeed connector that can transmit high-speed media data. The previous connectors have focused only on a physical connection and a mechanical reliability. However, as the data rate is increased, electrical performances of the connector have also become highly important. Therefore, signal integrity (SI) analysis for insertion loss, attenuation-to-crosstalk ratio (ACR), and impedance mismatch become essential for the high-speed connector. For verification, the 3D EM simulation tool is used to compare the performance of the previous and proposed connector. In conclusion, the proposed high-speed connector has better electrical performances than that of the previous connector.
