At maximum supply voltage with highly active input signals.
The data is for both input and output direction.
If an internal oscillator is used, crystal deviation of nominal frequency is directly proportional to the deviation of
subcarrier frequency and line/field frequency.
For full digital range, without load, V
DDA
= 3.3 V. The typical voltage swing is 1.35 V, the typical minimum output
voltage (digital zero at DAC) is 0.2 V.
Referring to peak-to-peak analog voltages resulting from identical peak-to-peak digital codes.
