Texas Instruments SN65DP149/SN75DP149 3.4Gbps DP++ to HDMI Retimer

Texas Instruments SN65DP149/SN75DP149 3.4Gbps DP++ to HDMI Retimer is a dual-mode DisplayPort to transition-minimized differential signal (TMDS) retimer. They support digital video interface (DVI) 1.0 and high-definition multimedia interface (HDMI) 1.4b output signals. The SN65DP149/SN75DP149 also supports the dual-mode standard version 1.1 type 1 and type 2 through the DDC link. These devices support data rates up to 3.4Gbps per data lane to support Ultra HD (4K×2K/30Hz) 8-bits per color high-resolution video and HDTV with 16-bit color depth at 1080p (1920×1080/60Hz). They can automatically configure themselves as a re-driver at data rates < 1Gbps, or as a retimer at more than this data rate. This feature can be turned off through I2C programming.
