Breadboard-tool: oscillator module

I recently build a small module consisting of a LTC6990 voltage controlled oscillator. This chip can generate square waves ranging from 488Hz up to 2MHz, and is controlled by a voltage divider an a set resistor:

For some more explanations see my blog entry for it. Its rather small, and needs only three pins to be put into a breadboard. I think it is a nice addition to my toolbox. It's not as accurate as my crystal-based generator (which still waits for a blog entry), but much smaller...
