TPD12S015
The TPD12S015 is an integrated HDMI ESD solution. The device pin mapping matches
the HDMI type C/D connector with four differential pairs. This device offers eight low-
capacitance ESD clamps, allowing HDMI 1.3 data rates. The integrated ESD clamps
and resistors provide good matching between each differential signal pair, which allows
an advantage over discrete ESD clamp solutions where variations between ESD clamps
degrade the differential signal quality.
