This simplifies the power tree in mixed-voltage designs and reduces BOM count. ## Package – 6-SMD no-lead, 3.2mm x 2.5mm Housed in a 6-SMD no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm. The small footprint suits space-constrained PCBs in automotive ECUs, ADAS modules, and industrial sensor nodes.","metaTitle":"DSC1121CI2-027.0000 MEMS Oscillator – 27 MHz, AEC-Q100","metaDescription":"Microchip DSC1121CI2-027.0000: 27 MHz XO, MEMS resonator, CMOS output, AEC-Q100 qualified, -40°C to 85°C, 2.25V-3.6V supply, enable/disable.
