8.2.1 Design Requirements

For this design example, 8 ESD341 devices and 5 TPD1E05U06 devices are being used in an HDMI 1.4

application, which provides a complete port protection scheme.

Table 8-1 lists the parameters for the HDMI 1.4 application.

8.2.2 Detailed Design Procedure

8.2.2.1 Signal Range

The ESD341 supports signal ranges between –3.6 V and 3.6 V, which supports the TMDS signals. The

TPD1E05U06 supports signal ranges between 0 V and 5.5 V, which supports the other signals (CEC, UTILITY,

DDC CLK, DDC DAT, and HOTPLUG_DET) in the HDMI 1.4 application.

8.2.2.2 Operating Frequency

The ESD341 has a 0.66 pF (typical) capacitance, which supports the 3.4 Gbps data rate needed for the HDMI

1.4 application.
