Crystal Source

Tried digikey?

Generically, try DigiKey

or Jameco for crystals but if you are looking for something like an oscillator, I found a great source in the Linear Technology LTC6900 chip. It's in an SOT-23-5 package (very small) and requires a single 0.1uF cap (which you ususally put on your oscillator anyway) and a single resistor. The resistor is used to program your desired frequency anywhere from 1KHz to 20MHz. It operates on a single supply voltage anywhere from 2.7VDC to 5.5VDC. The device runs on about 500uA. I ran a test with a PIC18LF252 operating at an external 10MHz with the internal 4X multiplier in the PLL (so the part was running at

40MHz) and an RS232 line running at 9600 baud into a HyperTerminal. The program sent a message to the serial port every second. It worked without error for the length of the test (over 6 hours).

The device cost about $1.50 each when I got 25 from Linear Technology directly.

Hope this helps.

Thanks for the advise. Glitchbuster looks great.
