4.3 Analog-to-Digital Converter (ADC)
The Analog-to-Digital block has the following features:
● Supports input clocks up to 140MHz (SXGA 75Hz)
● Adjustable analog amplifier bandwidth
● Differential RGB input path for noise immunity
● Built-in Sync-on-Green support
● Individual RGB clock delay control
● Power down control
● Linear and independent Gain/Offset adjustment.
GAIN CONTROL
Red, Green, and Blue channels have independent control registers: ANA_ADC_RED_0,
ANA_ADC_GRN_0, and ANA_ADC_BLU_0, respectively.
