The DSC1121CL2-027.0000 is a 27 MHz MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a CMOS output across a wide 2.25V to 3.6V supply range.
The 2.25V to 3.6V supply range covers 2.5V and 3.3V rails without an external regulator, simplifying the power tree on mixed-voltage boards.
Functionally yes — it is a drop-in XO replacement with a CMOS output and the same 6-SMD footprint. The MEMS resonator offers better shock/vibration tolerance and tighter frequency stability over temperature than a basic quartz oscillator.
Yes, it carries AEC-Q100 rating, meaning it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up.
