The TPD12S520 is a single-chip electro-static discharge (ESD) circuit protection device
for the high-definition multimedia interface (HDMI) receiver port. While providing ESD protection
with transient voltage suppression (TVS) diodes, the TVS protection adds little or no additional
glitch in the high-speed differential signals. The high-speed transition minimized differential
signaling (TMDS) ESD protection lines add only 0.8-pF capacitance.
The low-speed control lines offer voltage-level shifting to eliminate the need for an
external voltage level-shifter IC. The control line TVS diodes add 3.5-pF capacitance to the
control lines. The 38-pin DBT package offers a seamless layout routing option to eliminate the
routing glitch for the differential signal pairs. The DBT package pitch (0.5 mm) matches with 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 HDMI
receiver-interface protection. The 24-pin RMN package offers flow through routing using only two
layers for highly integrated, space-efficient full HDMI protection.
