Notes:
1 AVCC stands for the termination supply voltage of the receiver, which is 3.3V +/- 5%.
2 Measured under typical conditions, at minimum differential clock frequency and maximum DVI/HDMI PLL VOC frequency.
3 Measured under typical conditions, based on typical leakage values.
4 Figure B-6 below illustrates some of the DC Characteristics of the LVTM interface in TMDS mode.
