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-.
Due to the extremely high rate of data transfer, the capacitance of the ESD suppressor must be minimized. Low-capacitance (devices under 0.5pF) such as the SP3010 series SPA TVS Diode Arrays or discrete PulseGuard ESD suppressors are recommended.
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.
The IEC 61000-4-2 will be the most appropriate standard that applies for this port. It supplies a test method for verifying that the end product is not susceptible to ESD events.
