A PCB Design Guideline to Prevent DVI Signaling Power-Reverting in the CH7009 Family Chips Applications Application Notes

PublishTime：2022-10-20

●This application note focuses on a special PCB design care for the CH7009 family (CH7009/CH7010/CH7301)DVI applications. When using the CH7009 family devices for DVI applications, system shut-down problems have been reported by customers in some PC motherboards. Typically, the PC would shut down properly if the DVI monitor is powered down first. However, if the DVI monitor remains powered on, occasionally, Windows may not shut down properly. This problem only occurs in some motherboard designs. Intel's ADD cards and nVidia's PDD cards have not shown this behavior. It is suggested that the motherboard designer follow this guideline to prevent the motherboard from having this system power-down sequence disorder.
