The DSC1121DE1-025.0012T is an active-production MEMS-based XO from Microchip's DSC1121 series, delivering a fixed 25.0012 MHz output with CMOS drive levels. The wide supply range of 2.25V to 3.6V lets it run directly from a 2.5V or 3.3V rail without an intermediate LDO, simplifying the power tree.
Fit check: frequency, stability, and enable control
Packaged in a 2.50 mm x 2.00 mm 6-SMD no-lead footprint, the DSC1121DE1-025.0012T is a drop-in replacement for quartz oscillators of the same size and pinout — no board layout change needed.
