AD8191 The length of cable that can be used in a typical HDMI/DVI application depends on a large number of factors, including: • Cable quality: the quality of the cable in terms of conductor wire gauge and shielding. Thicker conductors ...
Page 27
Furthermore, to prevent unwanted signal coupling and interference, route the TMDS signals away from other signals and noise sources on the PCB. Both traces of a given differential pair must be equal in length to minimize intrapair skew. Maintaining ...
