Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality.
The TPD1E04U04 is a diode type TVS which is used to provide a path to ground for dissipating ESD events on high-speed signal lines between a human interface connector and a system. As the current from ESD passes through the TVS, only a small voltage drop is present across the diode. This is the voltage presented to the protected IC. The low RDYN of the triggered TVS holds this voltage, VCLAMP, to a safe level for the protected IC.
For this design example eight TPD1E04U04 devices and five TPD1E05U06 devices are being used in a HDMI 2.0 application. This provides a complete ESD protection scheme.
Given the HDMI 2.0 application, the parameters listed in Table 1 are known.
|Signal range on TMDS lines||0 V to 3.6 V|
|Operating frequency on TMDS lines||up to 3 GHz|
|Signal range on control lines||0 V to 5.5 V|
The TPD1E04U04 supports signal ranges between 0 V and 3.6 V, which supports the TMDS pairs on the HDMI 2.0 application. The TPD1E05U06 supports signal ranges between 0 V and 5.5 V, which supports the control lines.
The TPD1E04U04 has a 0.5-pF (typical) capacitance, which supports the HDMI 2.0 data rates of 6-Gbps. The TPD1E05U06 has a 0.5-pF (typical) capacitance as well, which easily supports the control line data rates.
