The MEMS resonator inherently withstands higher vibration and mechanical shock than a quartz crystal, which is why this series is common in ADAS camera modules, engine control units, and infotainment head units that see constant vibration. The 2.25V to 3.6V supply range covers both 2.5V and 3.3V logic rails without an external regulator — useful when the same BOM position must work across multiple power domains. Max active supply current is 35 mA — budget this into the power tree; the enable pin is referenced to Vdd, so a logic-high enables the output. Housed in a 6-SMD, No Lead package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — the 6-pad footprint is a standard MEMS oscillator land pattern, compatible with most reflow profiles for lead-free assembly.","metaTitle":"DSC1121NE5-066.6660T MEMS XO – Microchip, AEC-Q100","metaDescription":"Microchip DSC1121NE5-066.6660T MEMS oscillator: 66.666 MHz, ±10 ppm stability, CMOS output, AEC-Q100 qualified.
