25 MHz MEMS XO — 1.8V, LVCMOS, ±50 ppm
The DSC1525JI1A-25M00000: Operating from a single 1.8V supply and drawing a maximum of 7.5 mA, it suits low-power digital cores and battery-backed real-time clock domains where the 1.8V rail is already present.
MEMS resonator vs quartz — package and shock profile
This matters for portable instrumentation, automotive infotainment, or any board that sees mechanical vibration during shipping or operation. Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm, the footprint is smaller than a typical quartz SMD oscillator — the 0.50 mm pitch pads require a clean solder-paste stencil aperture to avoid bridging.
Microchip lists the DSC1525JI1A-25M00000 as Active.
