What does "IF" in "IF voltage" stand for?
It is really not easy to find information about this module, and there seems to be no datasheet available online! Only product brief and some fragmented data. But here's the answer to your question, however for slightly different model

Power supply
  Analog    2.5V
  Digital   1.1V
  Interface 1.8V


Here's one more. Funny enough lack of information about product should play bad joke with Sony.
