Pin Description
(3.3 V) Supply for Analog (Pixel PLL Circuitry).
This pin supplies 3.3 V to the analog portions of the pixel PLL circuitry.
(3.3 V) Supply for Analog ADC (Circuitry).
These pins supply 3.3 V to the analog portions of the ADC.
(3.3 V) Supply for Digital (Pixel PLL and Industry-Standard 2-Wire Serial Bus) Circuitry.
This pin supplies 3.3 V to the digital pixel PLL and circuitry for an industry-standard 2-wire serial bus
interface.
(3.3 V) Supply for Digital ADC (Circuitry).
This pin supplies 3.3 V to digital portions of the ADC.
(3.3 V) Supply for Memory Clock.
This pin supplies 3.3 V to the memory clock PLL circuitry.
(3.3 V) Supply for Panel Clock.
This pin supplies 3.3 V to the panel clock PLL circuitry.
(3.3 V) Supply for Output Drivers.
This pin supplies 3.3 V to the output driver circuitry for the pixel PLL.
(3.3 V) Supply for Output Drivers for Analog-to-Digital Converter.
These pins supply 3.3 V to the pixel data output drivers of the ADC.
(3.3V) Supply for Crystal Oscillator.
This pin supplies 3.3 V to the internal crystal oscillator circuitry.
Voltage Reference Bottom.
The ADC uses this pin as a bottom reference voltage. Typically, this pin is grounded.
Voltage Reference Top Blue, Green, Red
• The ADC uses these pins as an alternative to the blue, green, and red top reference voltages
from the internal DACs.
• Each of these pins must connect to its own separate bypass capacitor.
