This document describes the features and characteristics of the STDVE003A adaptive 3.4 Gbps 3:1 TMDS/HDMI signal equalizer.
The STDVE003A is an adaptive 3.4 Gbps 3:1 TMDS/HDMI signal equalizer designed for high-definition multimedia interface applications. It integrates a 4-channel equalizer and a 3:1 switch to select one of three HDMI ports, supporting video formats with deep color at maximum refresh rates up to 340 MHz clock speed. The device includes features such as fully automatic adaptive equalization, integrated open-drain buffers for the display data channel (DDC), and on-chip selectable 50 Ω input termination to improve signal integrity over long PCB track lengths.
The datasheet provides detailed specifications for the device, including absolute maximum ratings, DC and dynamic electrical characteristics for TMDS differential inputs and outputs, and I2C repeater parameters. It also covers application information regarding power supply sequencing, differential trace requirements, and package mechanical data for the TQFP80 package.
