50 Mhz Resonater

crgwbr

Hey Everyone,
I'm desinging a board with an SX28 on it.· I need to put a 50 MHz resonater on the board as well, however I can't find anything on the pinout of these.· Does anyone know what the pinout is, or better yet, how to hook it to·an SX28 permetly,·and·still be able to reprogram it with the SX-Blitz?

Thanks

Look on pages 176 - 178 in the SX-Key/Blitz Manual, and see if that helps. I was just looking at that an hour ago!.

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.
