Dan and the gang,

in my post, I mentioned an external clock generator, and not a resonator. Such clock generators require a supply voltage, and deliver the desired clock on one output pin. This pin should go to the OSC1 pins of the SX devices with the OSC2 pin left open on all of these devices.

I'm pretty sure that a resonator with its outer two pins wired to the OSC1/OSC2 pins of two or more SXes will not work.

According to the SX28 datasheet, the OSC1 pin is defined as "Crystal oscillator input - external clock source input", and OSC2 is defined as "Crystal oscillator output". I never tried it, but this might work: Connect a resonator to the OSC1/OSC2 pins of one SX, and wire its OSC2 pin to the OSC1 pins of the other SXes (with OSC2 left open on these devices). I could not find a specification which load the OSC2 output pin can drive, i.e. if and how many additiona SXes it can clock. Seems as if some experimenting is in order here.

[/quote]Guys,
 

I have a physical barrier that prevents me from using wires. I would switch to a more stable osc, but

they are not robust enough...

 

The SAW oscillators with a frequency divider may be an option...
