Didn't someone say to never use Maxim? I wish I'd listened. I'm working on a little project using their DS1077 clock generator IC, and have been tearing my hair out for a day trying to figure out why the board isn't working properly. It turns out from searching the web that a lot of people have this problem - I found a forum post by a fellow who was in contact with Maxim who said you have to write settings via I2C to the chip in a specific non intuitive way or it doesn't function properly. Of course, not mentioned in the datasheet at all. Also certain pins seem to have weird undocumented functions that also aren't mentioned.
Unfortunately. it's like the datasheet is someone's fantasy of how the part should work, while the actual part has so many weird quirks as to make the it almost unusable. Unless I can get in contact with someone who has working C code I'm going to have to hope some Maxim engineer can go over my code line by line to see what I'm doing wrong.
