The DSC1121CE5-025.0000T is an active-production MEMS-based XO (Standard) from Microchip’s DSC1121 series, delivering a 25 MHz CMOS output with ±10 ppm frequency stability over its -20°C to +70°C operating range. Its AEC-Q100 qualification means it is ready for automotive-grade designs — under-hood or cabin electronics that must survive temperature cycling and vibration without frequency drift.
Supply voltage range and power rail compatibility
The supply voltage range of 2.25 V to 3.6 V covers both 2.5 V and 3.3 V logic rails without requiring an external LDO — a single rail serves the oscillator and the downstream CMOS load.
Package, footprint, and board-level fit
Housed in a 6-SMD, no-lead package measuring 3.20 mm x 2.50 mm (0.126" x 0.098") with a seated height of 0.90 mm (0.035"), this oscillator fits standard 3.2 x 2.5 mm XO footprints and is compatible with reflow soldering profiles.
