ESD protection for HDMI 1.3 Design How-To 7/27/2007 Post a comment The higher the data speed and the more advanced the process technology, the harder it is to protect the IC from over-voltage stresses caused by ESD or CDE. As a result, HDMI designs often include additional transient protection to ensure the IC's reliability. Adding external transient protection for HDMI is difficult, however, due to HDMI's sensitivity to signal integrity. Each additional device added to the signal line implies extra parasitic elements that can affect signal transmission.
