Notes
1. At maximum supply voltage with highly active input signals.
2. The data is for both input and output direction.
3. With LLC in input mode. In output mode, with a crystal connected to XTALO/XTALI duty factor is typically 50%.
4. If an internal oscillator is used, crystal deviation of nominal frequency is directly proportional to the deviation of
subcarrier frequency and line/field frequency.
5. 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.
