CH7xxx PCB Design Considerations of DAC outputs with Multiple Video Formats Technical Bulletin 45

PublishTime：2022-10-20

●Picture ringing and connection detection failure may occur on the RGB bypass, CVBS, or s-video output because of improper implementation of the CH7xxx DACs. CH7xxx in this document refers to the following Chrontel Encoders: CH7009/CH7010/CH7011/CH7012, CH7015, CH7017, CH7019, CH7205, CH7301, and CH7303. This Technical Bulletin addresses the case in which two video reconstruction filter circuits are connected to a DAC intended to drive more than one type of video signals. When two filter circuits are connected to a DAC, the DAC connection detection scheme may also be affected
