FUNCTION
Channel C Input 1. AC-couple INC1 with a series 0.1µF capacitor.
Analog Ground. Connect all AGND pins to the ground plane. See the Power-Supply Bypassing and
Layout Considerations section.
Channel A Input 2. AC-couple INA2 with a series 0.1µF capacitor.
Channel B Input 2. AC-couple INB2 with a series 0.1µF capacitor.
Channel C Input 2. AC-couple INC2 with a series 0.1µF capacitor.
Channel A Input 3. AC-couple INA3 with a series 0.1µF capacitor.
Channel B Input 3. AC-couple INB3 with a series 0.1µF capacitor.
Channel C Input 3. AC-couple INC3 with a series 0.1µF capacitor.
Digital Ground. See the Power-Supply Bypassing and Layout Considerations section.
Channel A External Sync Input. Connect to ground if not used.
Channel B External Sync Input. Connect to ground if not used.
Channel C External Sync Input. Connect to ground if not used.
I2C-Compatible Serial Clock Input
I2C-Compatible Serial Data Input/Output
Digital Power Supply. Bypass to DGND with a 0.1µF capacitor. See the Power-Supply Bypassing and
Layout Considerations section.
Video Output 3. OUT3 can be either AC- or DC-coupled.
Analog Power Supply. Bypass each AVDD input to AGND using a 0.1µF capacitor. See the Power-
Supply Bypassing and Layout Considerations section.
