Circuit protection of HDMI interface

Circuit protection of HDMI interface
Design Notes:
Protection application:
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
Solution description:
Due to the extremely high data transfer rate, the capacitance of the ESD suppressor should be minimized. Low-capacitance (devices under 0.5pF) such as the SP3010 series SPA TVS Diode Arrays or discrete PulseGuard ESD suppressors are recommended.
Supporting solutions:
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.
Regulatory issues:
IEC 61000-4-2 is the standard specification most suitable for this interface. This test proves that the end product is not vulnerable to ESD.
Features:
Application warning: Not applicable.
