The MEMS resonator replaces a quartz crystal and its load capacitors, so the oscillator starts faster and is less sensitive to board layout parasitics — a single 2.50 mm x 2.00 mm 6-SMD no-lead package delivers the clock without external tuning. ## Supply range and enable/disable — power-tree flexibility The supply voltage spans 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V logic rails without a dedicated regulator — one BOM line serves multiple voltage domains. ## AEC-Q100 and industrial temperature — deployment envelope","metaTitle":"DSC1121DI2-011.0590 MEMS XO, 11.059 MHz, CMOS, AEC-Q100","metaDescription":"Microchip DSC1121DI2-011.0590 MEMS oscillator, 11.059 MHz, CMOS output, ±25 ppm, 2.25-3.6 V, -40 to 85°C, AEC-Q100.
