EXTERNAL DC REFERENCE LEVELS
122
V_CHROMAx2_INA
Analog Input. Chroma Reference Level for DC-Restore when A_V = 2, for Channel A. This DC voltage sets
the midpoint voltage of the C signal (S-Video) and the Pb, Pr signals (Component video) for Channel A when
the gain is set to x2. When using the YPbPr inputs in YPbPr mode, this DC voltage sets the clamp voltage
of the Pr/R and Pb/B signals for Channel A. This input is typically tied together with V_CHROMAx2_INB and
driven with the same voltage.
121
V_CHROMAx1_INA
Analog Input. Chroma Reference Level for DC-Restore when A_V = 1, for Channel A. This voltage sets the
midpoint voltage of the C signal (S-Video) and the Pb, Pr signals (Component video) for Channel A when
the gain is set to x1. When using the YPbPr inputs in YPbPr mode, this DC voltage sets the clamp voltage
of the Pr/R and Pb/B signals for Channel A. This input is typically tied together with V_CHROMAx1_INB and
driven with the same voltage.
