The base resonator is MEMS, not quartz — which means no crystal aging drift and no start-up time penalty on power-up. Supply voltage spans 2.25V to 3.6V — a single oscillator covers 2.5V and 3.3V logic domains without a rail translator, which simplifies the BOM for mixed-voltage designs. ## Design-in checklist: package, power, and enable An Enable/Disable function lets the system gate the clock — when disabled, supply current drops to 22 mA max, useful for power-save modes in battery-backed equipment. Frequency stability is ±50 ppm across temperature and supply — no external trim capacitors or tuning needed; the MEMS factory-calibrated output hits the target frequency on first power-up. ## Active production, sourced per RFQ Sourced through independent distribution against your BOM quantity. Tape & Reel (TR) packaging for automated pick-and-place.","metaTitle":"DSC1121AL1-041.5000T MEMS Oscillator 41.5 MHz CMOS -","metaDescription":"DSC1121AL1-041.5000T XO (Standard) MEMS oscillator, 41.5 MHz, CMOS output, 2.25-3.6V, -40 to 105°C, 6-VDFN.
