5.12.5
Before Digital-to-Analog conversion an adjustment of the phase of the luminance signal
can be performed (I²C Bus parameter COARSDEL, 5Ch). The delay of the luminance
can be varied by periods (-8, ...[1]... , +7) of the DAC clock (2*CLKD). This can be used
to compensate different delay times of external analog filters.

Three 9-bit Digital-to-Analog converters are implemented. The DACs are short-circuit
protected converters with current outputs. The full range output current of the IY_O,

with lower requirements there is still another way to define I
the positive supply and apply a resistor against ground. Since in this operation mode the
internal reference amplifier reaches saturation, the exact value of I
