摘要
高清多媒体接口(HDMI)技术正在迅猛的增长,传输速率也越来越快,遇到的高速连接的挑战也越来越大。通过时域反射(TDR)技术对HDMI的高速差分总线进行特性阻抗测量,可以直接的测量和显示印刷电路板(PCB)走线以及连接器和线缆的阻抗连续性能,对于诊断和分析HDMI系统高速连接的可靠性和稳定性起到非常重要的作用。
The HDMI technology is growing rapidly with faster and faster data transmission.At the same time,the high-speed connection of HDMI is also facing a greater challenge than before.The impedance of HDMI high speed differential bus can be good measured by the TDR technology.The TDR equipment can measure the impedance continuity performance of PCB traces、connectors and cables by a very intuitive view.The TDR is playing a very important role in reliability and stability of HDMI high-speed connection system.
