3.2 Muxes for High Speed Video Systems (HDMI, Displayport)

HDMI and DisplayPort are high-speed video interfaces for transmitting uncompressed video data from an HDMI or DisplayPort source device to a compatible computer monitor, video game console, or HDTV. The HDMI and DisplayPort signal consist of four low-voltage differential signal (LVDS) pairs for the red, green, blue (RGB) video. An ideal HDMI and DisplayPort mux contains four differential pairs of 1:2 or 2:1 muxes with high bandwidth to avoid degrading video quality.

The Niquist frequency of HDMI 2.0 is 3 GHz, and 4 GHz for DP1.4. For some analog muxes TI offers for HDMI and DisplayPort video applications, see Table 3-3.
