The DSC1121BM1-025.0000 is a 25 MHz MEMS-based standard oscillator (XO) from Microchip's DSC1121 series, delivering a CMOS output from a 2.25V to 3.6V supply rail.

That 13 mA saving matters in a battery-backed real-time clock or a sensor node that sleeps between reads.
Housed in a 6-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm max. The 0.197" x 0.126" footprint matches the common 5x3.2 mm oscillator land pattern — no via-in-pad required, and the no-lead construction keeps the parasitic inductance low for clean clock edges into a CMOS load.
