Frequently asked questions
Does the DSC1001DL2-003.9000 have AEC-Q100 qualification?
Yes, it carries AEC-Q100 ratings, making it suitable for automotive applications where temperature and reliability screening are required.
How does the standby power-down function work on the DSC1001?
The standby (power down) function disables the output and reduces supply current to 15 µA max. The oscillator stops; a logic-level on the enable pin restarts it within the start-up time specified in the datasheet.
Is a MEMS oscillator more reliable than quartz for automotive use?
MEMS resonators typically offer better shock and vibration tolerance than quartz crystals, and the DSC1001's AEC-Q100 qualification confirms it meets automotive reliability stress tests. For under-hood environments where quartz may exhibit frequency shift under vibration, MEMS is a common alternative.
