1. 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 1.4 V. 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.
