VGA port protection scheme
一、 The application background
1. The VGA needs to support hot plug;
2. The VGA transmission rate is maximum 8 GPBS;
3. The VGA chip fragile, easily electrostatic damage,
二、 The scheme in this paper
1. In the scheme of VGA cable, the clock frequency, etc on a transmission line with two TVS, low capacitance, reduce packaging area, electrostatic voltage clamp, can complete the transmission signal.
2. Meet IEC61000-4-2 electrostatic test standard.
3. Can through the ESD IEC61000-4-2 Level 4 Contact Discharge: 8 kv, Air Discharge: 15 kv test.
三、 Project information is as follows:
