DESCRIPTION/ORDERING INFORMATION  
The TPD12S520 is a single-chip ESD solution for the high-definition multmedia interface (HDMI) receiver port. In  
many cases, the core ICs, such as the scalar chipset, may not have robust ESD cells to sustain system-level  
ESD strikes. In these cases, the TPD12S520 provides the desired system-level ESD protection, such as the the  
IEC61000-4-2 (Level 4) ESD, by absorbing the energy associated with the ESD strike.  
While providing the ESD protection, the TPD12S520 adds little or no additional glitch in the high-speed  
differential signals (see Figure 3 and Figure 4). The high-speed transition minimized directional signaling (TMDS)  
lines add only 0.9 pF capacitance to the lines. In addition, the monolithic integrated circuit technology ensures  
that there is excellent matching between the two-signal pair of the differential line. This is a direct advantage over  
discrete ESD clamp solutions where variations between two different ESD clamps may significantly degrade the  
differential signal quality.  
The low-speed control lines offer voltage level-shifting to eliminate the need for an external voltage-level shifter  
IC. The control line ESD clamps add 3.5pF capacitance to the control lines.  
The 38-pin DBT package offers seamless layout routing option to eliminate the routing glitch for the differential  
signal pair. DBT package pitch (0.5 mm) matches the HDMI connector pitch. In addition, the pin mapping follows  
the same order as the HDMI connector pin mapping. This HDMI receiver port protection and interface device is  
designed specifically for next-generation HDMI receiver-interface protection.
