NOTE:
It is recommended that the digital portion of the CMI9738 component be capable of operating at
either 3.3V (+/- 5%), depending on which DVdd is supplied.However, the following has been added
to simplify the implementation for those who do not support dual voltage (and possibly those who
do), by allowing 5.0 or 3.3 V parts to match the PCI 2.2 specifications for Vih, Vil, Voh, and Vol:
