Pin Function Description
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.
