Frequently asked questions
Is DSC1121AI2-162.0000 a direct replacement for a standard quartz oscillator?
Pin-compatible with many 6-pin quartz XOs in the same 7×5 mm footprint, but the MEMS resonator has different startup behaviour — no external load capacitors are needed (the MEMS die is self-contained), and the Enable/Disable function is active-low on this part. Confirm the logic polarity of the OE pin on the quartz part you are replacing before swapping.
What is the frequency stability of DSC1121AI2-162.0000?
This includes initial tolerance, temperature drift, and supply-voltage variation — no aging term is added because the MEMS resonator does not exhibit quartz aging.
Does DSC1121AI2-162.0000 require an external load capacitor?
No. The MEMS resonator and oscillator circuit are integrated inside the package — the output is a CMOS square wave that drives the load directly. No external load capacitors or feedback resistors are needed.
