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 I
2
C 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 I
2
C_EN pin, this logic block can be enabled to indicate the translated port is an HDMI port; therefore legally
supporting HDMI content.
