Analog power (3.3V) for the red channel. Must be bypassed with decoupling capacitor to
AGND_RED pin on system board (as close as possible to the pin).
Positive analog input for Red channel.
Negative analog input for Red channel.
Analog ground for the red channel.
Must be directly connected to the analog system ground plane.
Analog power (3.3V) for the green channel. Must be bypassed with decoupling capacitor to
AGND_GREEN pin on system board (as close as possible to the pin).
Positive analog input for Green channel.
Negative analog input for Green channel.
Analog ground for the green channel.
Must be directly connected to the analog system ground plane.
Analog power (3.3V) for the blue channel. Must be bypassed with decoupling capacitor to
AGND_BLUE pin on system board (as close as possible to the pin).
Positive analog input for Blue channel.
Negative analog input for Blue channel.
Analog ground for the blue channel.
Must be directly connected to the analog system ground plane.
Analog power (3.3V) for ADC analog blocks that are shared by all three channels. Includes
band gap reference, master biasing and full-scale adjust. Must be bypassed with
decoupling capacitor to AGND_ADC pin on system board (as close as possible to the pin).
Analog test output for ADC Do not connect.
Analog ground for ADC analog blocks that are shared by all three channels. Includes band
gap reference, master biasing and full-scale adjust.
Must be directly connected to analog system ground plane.
Dedicated pad for substrate guard ring that protects the ADC reference system.
Must be directly connected to the analog system ground plane.
Digital GND for ADC clocking circuit.
Must be directly connected to the digital system ground plane
Digital power (2.5V) for ADC encoding logic. Must be bypassed with decoupling capacitor to
GND1_ADC pin on system board (as close as possible to the pin).
Digital GND for ADC clocking circuit.
Must be directly connected to the digital system ground plane.
Digital power (2.5V) for ADC encoding logic. Must be bypassed with decoupling capacitor to
GND2_ADC pin on system board (as close as possible to the pin).
