The frequencies are factory-programmed and not field-adjustable."},{"question":"Is this a MEMS oscillator?","answer":"Yes — the base resonator is MEMS, not quartz. That means faster startup, better shock tolerance, and no crystal aging drift over the first year."},{"question":"What is the closest pin-compatible alternative to the DSC400-1111Q0084KE1?","answer":"No direct pin-compatible alternative is listed in the DSC400 series with the same four-frequency set.
