The MEMS resonator replaces a quartz crystal, giving faster start-up and better shock resistance compared to a traditional crystal oscillator. ## Supply voltage range and enable/disable function Operates from a 2.5 V to 3.3 V supply, covering the common core rails for FPGAs, SoCs, and Ethernet PHYs — no extra regulator needed when the rail falls within that window. Built-in enable/disable pin lets the system gate the clock output without a separate load switch; disable current is 23 µA typical, useful for power-sensitive sleep modes. ## Package and mounting – 6-VDFN 2.5 mm × 2.0 mm Housed in a 6-VDFN package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits tight board layouts common in automotive camera modules or portable instrumentation. Surface-mount assembly with standard reflow profiles; the small body reduces parasitic capacitance on the output trace compared to larger SMD packages. ## Lifecycle – active production The part is available for both new designs and production replenishment through independent distribution.","metaTitle":"DSC1221DI3-148M5000T MEMS XO – Microchip, 148.5 MHz","metaDescription":"Microchip DSC1221DI3-148M5000T MEMS XO: 148.5 MHz, CMOS output, ±20 ppm stability, AEC-Q100 qualified.
