DESCRIPTION
The SN75DP139 is a Dual-Mode DisplayPort input to Transition-Minimized Differential Signaling (TMDS) output.
The TMDS output has a built in level shifting re-driver supporting Digital Video Interface (DVI) 1.0 and High
Definition Multimedia Interface (HDMI) 1.4b standards. The SN75DP139 is specified up to a maximum data rate
of 3.4Gbps, supporting resolutions greater then 1920x1200 or HDTV 12 bit color depth at 1080p (progressive
scan). SN75DP139 is compliant with the HDMI 1.4b specifications and supports optional protocol enhancements
such as 3D graphics at resolutions demanding a pixel rate up to 340MHz.
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 allows for considerable
design margin within the source system for DVI / HDMI compliance testing.
A logic block was designed into the SN75DP139 in order 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.
