TPD12S521DBTR, Микросхема защиты HDMI интерфейса от электростатических разрядов 38TSSOP

Описание TPD12S521DBTR

The TPD12S521DBTR is a HDMI Transmitter Port Protection and Interface Device, single-chip electro-static discharge (ESD) circuit protection device for the high-definition multimedia interface (HDMI) transmitter 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 signalling (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 3.5pF 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 (0.5mm) matches with the HDMI connector pitch. In addition, the pin mapping follows the same order as the HDMI connector pin mapping.
