LMX2582: Vacuum and VCO type

Part Number: LMX2582

Hello,

Can the LMX2582 be used in a vacuum? What type of VCO is inside of the LMX2582?

Thanks,

Matt

    Hi Matt,

    The LMX2582 uses LC-VCO cores which will work in a vacuum. The biggest difference between pressurized/vacuum operation is the thermal transient curve (no convection), so if there are rapid changes to device temperature you may see mildly exaggerated transient response while the temperature compensation tracks the changing device temperature.

    To be clear: I am distinguishing between terrestrial vacuum (created through a pump or other mechanism) and extraterrestrial vacuum. LMX2582 is usable in terrestrial vacuum. Extraterrestrial vacuum has additional radiation considerations which would mostly appear as transient VCO noise, but for higher energy radiation there could be other issues relating to the included digital circuits, such as VCO calibration registers spontaneously flipping bits. I only mention all this in case your question was a roundabout way of asking if the device could operate in an extraterrestrial environment; the vacuum would not present problems, but the other environmental factors could.

    Regards,
