3 Description
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.
