In SX Microcontrollers, SX/B Compiler and SX-Key Tool, Chris Savage wrote: Hello, The resonators we carry all have the same pinout. The center pin is ground and the outer pins go to the OSC pins on the SX. Polarity is not an issue, however if you check some of our schematics you will find that we usually add a small capacitor to the OSC2 side of the resonator...This makes the clocking more stable and at 50 MHz we use 5pF on that resonator. I hope this helps. Take care. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=146366#m146389 Need assistance?
