Design and Measurement of a HDMI 2.1 Connector for 8K TV considering Signal Integrity
In this paper, we propose the design of a HDMI 2.1 connector for 8K TV considering signal integrity (SI). Also, we firstly measure the proposed HDMI 2.1 connector. To achieve the high data rate, connector should be designed by considering not only mechanical characteristics but also electrical characteristics. We design the HDMI 2.1 connector considering SI including characteristic impedance, differential insertion loss and attenuation to crosstalk ratio (ACR). We revise the structure of metal pins and dielectric materials for improving the SI performances. Proposed HDMI 2.1 connector was verified by time-domain and frequency domain simulation using the 3D electromagnetic (EM) simulator. Proposed HDMI 2.1 connector showed improve SI performance than previous connector. Also, proposed connector was verified through measurement. With the proposed HDMI design, it shows better SI characteristics at the 24 Gbps which is expected to next generation HDMI connector’s data rate.
