Since summer arrived I have more time to return to using SASM.
This is really an oddball question.

 

I bought a programming adapter fro 3.3volt operation and I am changing the 5V supply on some of my SX48 Protoboards to 3.3 for cool running.  I can easily get up to 50mHz with resonators on hand.

 

I previously purchased several 75mHz tincan oscillators and I see they are +5V.  One thought is to just run them at 3.3volts, but I suspect that might not work.  

 

Though I cannot seem to figure a way to run the Protoboard as a dual voltage supply, I am also considering creating another board that might provide dual voltages with an SX-28.

 

Is there any problem with providing +5volts to the oscillator and +3.3 to the Vdd on the SXes?  And, would this really run the devices cooler and with less power consumption?
