HDMI ESD Protection
Two essential functions that customers look for in HD video systems are fast data processing and high-speed interface. Advances in data process technology are shrinking trace geometries and allowing for more performance and functionality to be included on ever-smaller integrated circuits (ICs). As for high-speed interface, High-Definition Multimedia Interface (HDMI) is the latest standard for devices that handle high-bandwidth, real time data, such as HDTV.
However, the higher the data speed and the more advanced the process technology are, the harder it is to protect the IC adequately from over-voltage stresses caused by ESD (electrostatic discharge) or CDE (cable discharge events). This is because the designated IC becomes more sensitive to the transient threats as the technology advances. As a result, HDMI designs often include additional transient protection to ensure the IC's reliability. Adding HDMI ESD protection 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.
