HDMI2.0 interface protection scheme

一、Scheme protection circuit diagram

 HDMI2.0接口防护方案

 

二、Application Environment

 Indoor HDMI2.0 interface protection

 

三、Explanation of the plan

1. HDMI2.0 is a high-speed signal, which has relatively high requirements on the capacitance value;

2. Three sets of OVEL608A1, 5V/0.5pF/DFN2510 packages are used for signal lines and control lines, which are more convenient to use;

3. A 5V/15pF/DFN1006 packaged device is used for the power cord, and the electrostatic protection capability is ±25KV for air; ±25KV for contact;

4. OVEL608A1 can withstand surges above 30V, and the electrostatic protection ability is ±25KV in air; contact ±25KV, the protection is more comprehensive;
