Stef,

    Here are a couple of random samples of what I am talking about.  If you go to your favorite parts supplier's Web site and search for "TTL Oscillator", you should find what you need.  They use a small amount of power and cost more than crystals or resonators but are quite reliable in operation.

    In use, you connect the output of the oscillator to the OSC1 pin of the SX chip and leave the OSC2 pin open (floating).  Program the FUSE Register for one of the XT clocking modes.
