Operating from 1.7 V to 3.6 V, the part covers 1.8 V, 2.5 V, and 3.3 V logic rails without a separate regulator — the wide input range simplifies BOM consolidation across multiple voltage domains. ## Surface-mount footprint and board layout Housed in a 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, the DSC1003DE1-040.0000 fits tight PCB layouts — the small footprint leaves room for decoupling capacitors near the supply pin.","metaTitle":"DSC1003DE1-040.0000 – 40 MHz MEMS XO, AEC-Q100, CMOS Output","metaDescription":"Microchip DSC1003DE1-040.0000: 40 MHz MEMS oscillator, ±50 ppm stability, AEC-Q100, 1.7-3.6 V supply, 7.4 mA max.
