I was planning on using an L3G4200D gyroscope in a project to align manufacturing rollers. I've been looking at the datasheet and it says that the clock rate is 10 MHz but it also has something about a "Output Data Rate" and it can be set to 100, 200, 400, and 800 Hz. That's way lower than the supposed clock rate so I was hoping someone could clear this up. I also don't understand what they mean when they say "Cut-Off" along with the ODR.

This is the product page, it has a link to download the datasheet (PDF)

The ODR is on page 29. The clock rate info is on page 12.

Note: We are using the SPI interface. (Almost forgot to mention that).
