设计说明:

保护应用:
The data signals used in High Definition Multimedia Interface ports vary between approximately 2.5V and 3.5V, and have a data rate of 1.6Gbps (1.3) or 3.4Gbps (1.4). The signal lines to be protected from ESD include D2+, D2-, D1+, D1-, D0+, D0-, CLK+ and CLK-.
解决方案说明:
由于数据传输率极高,应最小化ESD抑制器的电容量。 Low-capacitance (devices under 0.5pF) such as the SP3010 series SPA TVS Diode Arrays or discrete PulseGuard ESD suppressors are recommended.
配套解决方案:
For the lower speed I2C control lines, CEC bus, and Hot Plug Detect, a general purpose array like the SP1001-04XTG can be used or another SP3010-04UTG could be used for simplicity.
监管问题:
IEC 61000-4-2是最适合此接口的标准规范。 通过该测试可证明终端产品不易受到ESD危害。
特性:
应用警告:
不适用。
