40 MHz MEMS oscillator with automotive qualification
The DSC1003DE1-040.0000 is a 40 MHz MEMS-based XO (Standard) from Microchip's DSC1003 series, delivering CMOS output with ±50 ppm frequency stability across its -20°C to 70°C operating range.
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.
