This gives it better shock/vibration tolerance and faster startup than a quartz-based XO."},{"question":"What is the exact footprint and package type of the DSC2311KI1-R0046?","answer":"It comes in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The 6-pin DFN footprint is common across the DSC2311 family."},{"question":"Can the DSC2311KI1-R0046 replace a standard quartz oscillator?","answer":"Functionally yes — it outputs a standard CMOS clock at 19.2 MHz. The MEMS base resonator means it is more robust to vibration and starts faster than quartz, but the electrical interface (CMOS output, 2.25-3.6V supply) is the same.
