ESD Protection for DVI Ports
The industry’s demand for high-resolution flat panels requires more complex digital and analog solutions in a dense area. The small geometry’s of the digital-visual interface (DVI) graphic chip makes it more susceptible to electrostatic discharges (ESD) and cable discharge events (CDE). The industry ESD standard is IEC61000- 4-2. It requires the system to withstand 8kV contact and 15kV air ESD.
Transient protection of a DVI port can be challenging. Digital-visual interfaces can often transmit and receive at a rate equal to or above 1Gbps. The high-speed data transmission requires the DVI ESD protection device to have low capacitance to maintain signal integrity and low clamping voltage to reduce stress on the protected IC.
