GNDA, the negative voltage rail for the R, G and B diodes is not connected internally to GNDD. GNDA should

ideally be connected to the ground of the video DAC IC. This will prevent any ground bounce caused by digital

signals from injecting noise onto the R, G and B signals. Analog GND and digital GND are typically connected on the

printed circuit board.
