ADC Supply Voltages.
Provide a quiet noise free voltage.
PLL Supply Voltage.
Most sensitive supply voltage.
Provide a very quiet noise free voltage.
Digital Output Supply Voltage.
Decouple judiciously to
avoid propagation of switching noise.
Ground.
Returns for all power supplies. Connect ground
pins to a solid ground-plane.
Voltage Reference Input.
Common reference input to
RGB converters. Connect to VREFOUT, if internal
reference is used.
Voltage Reference Output.
Internal band-gap reference
output. Tie to ground through a 0.1μF capacitor.
