The datasheet is sparse yes but we have technical contacts at conexant who can answer your questions. The DC input mode was part of our early discussions with them and its supposed to work at least as good as the last chip did. I specifically remember asking them about this and telling them it was something to test in our early reviews of the hardware. It should work. If not then we need to know why so we can prevent it from happening on the 1.75. If you will frame up your questions with good detailed descriptions on how to duplicate the problems you are having I'll see that it makes it to conexant for testing and feedback and make sure they have the proper hardware to test it on. -- Richard A.
