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.
