Note:
DAC_POS, DAC_NEG, and DAC_REF are loaded with resistors to simulate video output driving into
a low pass filter and achieve a full output swing of 1.4V. Their resistor loadings may be different
from the loadings in a real single-ended or differential-ended video output system with an actual
receiving end. Please refer to the Developer Guide for proper resistor loadings.
