Other Parts Discussed in Thread: TVP5150
Tool/software: Linux
Hi:
Software version: TI_SDK 4.3, hardware version: AM5728-ES2.0, custom board
The tvp5150 input has two signal sources. The CD74HC4051M chip controls the signal source and finds that bad images appear when switching signals.
Tvp5150 uses embedded sync signal with a resolution of 720 * 288.
Test steps:
1. When I tested the tvp5150 two sources separately, the images were correct.
2 When the two signal sources are swapped back and forth during the TVP5150 acquisition process, a bad image of the connection will appear.

Do you have any way to make tvp5150 switch to the source without bad images?
Thanks
The schematic is as follows:
