I Substrate. Connect to analog ground.
AIP1A
Analog input. Connect to the video analog input via 0.1-µF capacitor. The maximum input range is 0−0.75
1
I VPP, and may require an attenuator to reduce the input amplitude to the desired level. If not used, connect
to AGND via 0.1-µF capacitor. Refer to Figure 5−1.
AIP1B
Analog input. Connect to the video analog input via 0.1-µF to capacitor. The maximum input range is 0−0.75
2
I VPP, and may require an attenuator to reduce the input amplitude to the desired level. If not used, connect
to AGND via 0.1-µF capacitor. Refer to Figure 5−1.
