2.YPbPr输入接口电路YPbPr输入接口电路如图5所示。从JPl01输入的Pb信号经电容C1066与R120组成的RC滤波网络后,通过电容C1080耦合到U105(MST515lA)的輮輦訛脚进行视频信号处理;从JPl01输入的Y信号经电容C1067与R121组成的RC滤波网络后,分为两路:一路通过电容C1094耦合到U105的輰輦訛脚进行视频信号处理。另一路通过电容C1082耦合到U105的輱輦訛脚进行视频信号处理;从JPl01输入的Pr信号经电容C1068与R122组成的RC滤波网络后,通过电容C1084
2.YPbPr input interface circuit YPbPr input interface circuit shown in Figure 5. The Pb signal input from JP101 is composed of capacitors C1066 and R120 and is then filtered by capacitor C1080 to the video signal of U105 (MST5151A). The Y signal input from JP101 is composed of capacitors C1067 and R121 RC filter network, divided into two: all the way through the capacitor C1094 coupled to the U1010 erroneous foot video signal processing. The other way through the capacitor C1082 coupled to the U105 辇 辇 the wrong foot video signal processing; Pr01 from the JP01 input signal through the capacitor C1068 and R122 composed of RC filter network, through the capacitor C1084
