Protect DisplayPort apps from ESD, CDE

Keywords:DisplayPort? open digital communication interface? ESD protection? CDE?

DisplayPort is a new graphics communications interface that seeks to do for the PC what HDMI did for the TV--display high-definition (HD) video content. And, as with HDMI, there are unique protection issues with DisplayPort designs stemming from the high speed of the interface and the constant threat of ESD and cable discharge events (CDE) from normal use.

The DisplayPort standard is an uncompressed, open digital communication interface that represents a cost reduction opportunity for PC makers by consolidating the internal and external interconnect. Internally, it is an interface within a PC or monitor. Externally, it connects a PC to a monitor, projector or TV. When used as an external interface, the DisplayPort plug is frequently exposed to ESD directly from the user or CDE from the hot plug cable.
