open-in-new Find other HDMI, DisplayPort & MIPI ICs


The SN75DP129 is a Dual-Mode DisplayPort input to Transition-Minimized Differential Signaling (TMDS) output. The TMDS output has a built-in level translator, compliant with Digital Visual Interface 1.0 (DVI) and High Definition Multimedia Interface 1.3 (HDMI) standards. The SN75DP129 is specified up to a maximum data rate of 2.5 Gbps, supporting resolutions greater then 1920 x 1200 or HDTV 12-bit color depth at 1080p (progressive scan).

An integrated Active I2C buffer isolates the capacitive loading of the source system from that of the sink and interconnecting cable. This isolation improves overall signal integrity of the system and provides greater design margin within the source system for DVI / HDMI compliance testing.

A logic block was designed into the SN75DP129 to assist with TMDS connector identification. Through the use of the I2C_EN pin, this logic block can be enabled to indicate the translated port is an HDMI port; therefore legally supporting HDMI content.
