Among the crystals I received, there is a couple of 1.8432 MHz integrated oscillators and I put them to the test today. The power is quite low : 2mW !

* The operating voltage looks pretty low : 2V !
* The operating current is just about 1mA.

I can pull/push the frequency with :

• adjusting the voltage : lower voltage => higher frequency
• adjusting the output load : tbd
• temperature : tbd

From the start it's working at a few Hz away from the expected/rated frequency and it's great. An integrated CMOS or TTL frequency divider would provide all the needed operating frequencies.
