I2C Arduino

Hello,
I have been reading the data sheet for the DS1077 and I am just not that knowledgable yet with the Arduino. My goal is to output a squarewave in an LC circuit. Right now my project works with the Parallax Propeller platform, but that requires an ADC (8 bit). The Arduino has built-in ADC. That could make my instrument much smaller. How does one know what to send or recieve to a chip to configure it? The chip: http://www.sparkfun.com/commerce/product_info.php?products_id=9116
Has anyone interfaced this chip yet? Software I mean.
Thanks,
Curtis
