The supply voltage range of 1.8V to 3.3V lets this oscillator drop into designs with a 1.8V core rail or a 3.3V I/O bank without a separate level translator. ## 5.0 mm × 3.2 mm no-lead package — footprint and reflow Housed in a 4-SMD no-lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm. Surface-mount assembly on standard FR-4 with a lead-free reflow profile is straightforward; no special bake-out or moisture sensitivity handling is required beyond the standard MSL level.","metaTitle":"DSC1001BI5-066.6666T MEMS Oscillator","metaDescription":"Microchip DSC1001BI5-066.6666T XO (Standard) MEMS oscillator, 66.6666 MHz, CMOS output, AEC-Q100 qualified, ±10 ppm stability, -40°C to 85°C.
