The DSC1101AM2-014.3950T is a fixed-frequency MEMS-based oscillator from Microchip, not a quartz crystal — the MEMS resonator is sealed at the die level, which gives it better shock and vibration immunity than a quartz can. The output is CMOS, so it drives a standard digital clock input without a level translator. Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails without an external regulator.
The ±25 ppm frequency stability holds across that entire band, not just at 25°C.
Listed as Active by Microchip. Sourced through independent distribution; quoted to order against the BOM quantity.
Standby function and package footprint
The Standby (Power Down) function pulls the output to high-impedance and drops the supply current to near zero — useful for battery-powered systems that gate the clock to save power. The package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm, a common footprint shared by many MEMS oscillators in this form factor.
