F TPD12S520 www.ti.com SLVS640F – OCTOBER 2007 – REVISED FEBRUARY 2015 8 Application and Implementation NOTE 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. 8.1 Application Information TPD12S520 provides IEC61000-4-2 Level 4 Contact ESD rating to the HDMI 1.4 receiver port. Integrated voltage-level shifting reduces the board space needed to implement the control lines. 8.2 Typical Application TPD12S520 is designed to protect a typical HDMI 1.4 receiver port. Refer to Figure 6 for a typical schematic. The eight TMDS data lines (D2+/-, D1+/-, D0+/-, CLK+/-) each have two pins on TPD12S520 to connect to. The TMDS data lines flow through their respective pin pairs, attaching to the passive ESD protection circuitry. Figure 6.
