DESCRIPTION
Analog Section
AGND 7 I Substrate. Connect to analog ground.
AIP1A 1 I
Analog input. Connect to the video analog input via 0.1-µF capacitor. The maximum input range is 0−0.75
V
PP
, 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 2 I
Analog input. Connect to the video analog input via 0.1-µF to capacitor. The maximum input range is 0−0.75
V
PP
, 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.
CH_AGND 31 I Analog ground
CH_AVDD 32 I Analog supply. Connect to 1.8-V analog supply.
PLL_AGND 3 I PLL ground. Connect to analog ground.
PLL_AVDD 4 I PLL supply. Connect to 1.8-V analog supply.
REFM 30 I
A/D reference ground. Connect to analog ground through 1-µF capacitor. Also recommended to connect
directly to REFP through 1-µF capacitor. Refer to Figure 5−1.
REFP 29 I A/D reference supply. Connect to analog ground through 1-µF capacitor. Refer to Figure 5−1.
