Datasheet

The High-Definition Multimedia Interface (HDMI) is provided for transmitting digital 
audio and video signals from DVD players, set-top boxes and other audiovisual sources 
to television sets, projectors and other video displays. It can carry high quality multi-
channel audio data and all standard and high-definition consumer electronics video 
formats. HDMI display interface connecting the processor and display devices utilizes 
transition minimized differential signaling (TMDS) to carry audiovisual information 
through the same HDMI cable.

HDMI includes three separate communications channels: TMDS, DDC, and the optional 
CEC (consumer electronics control) (not supported by the processor). As shown in 

, the HDMI cable carries four differential pairs that make up the TMDS data

I/O

This signal is used for pre-driver slew rate compensation.
An external precision resistor of 402 Ω ±1% should be connected between 

DDI_RCOMP_P and DDI_RCOMP_N.
