The 2.25V to 3.6V supply range lets this XO run directly from a 2.5V or 3.3V rail without an extra LDO — one less component in the power tree, and the CMOS output levels track the supply so no level translation is needed for the downstream logic. ±25 ppm frequency stability over temperature and supply variation is tight enough for a 40 MHz clock feeding a CAN FD controller or a 100BASE-T1 PHY — the total timing error budget for those interfaces is typically ±50 ppm or wider, leaving margin for the PLL jitter. ## Package and footprint — 2.5 mm x 2.0 mm 6-SMD Housed in a 6-SMD, No Lead package measuring 0.098\" x 0.079\" (2.50 mm x 2.00 mm) with a seated height of 0.035\" (0.90 mm), this oscillator fits into compact PCB layouts where board real estate is at a premium — typical for ADAS cameras, radar modules, or telematics control units. Surface-mount assembly with a no-lead land pattern means the PCB footprint is a simple pad array — no through-holes, no bent leads to inspect.","metaTitle":"DSC1121DL2-040.0000 – Microchip MEMS XO, 40 MHz, CMOS","metaDescription":"DSC1121DL2-040.0000 from Microchip Technology: 40 MHz MEMS XO, CMOS output, AEC-Q100 qualified, -40°C to 105°C, 2.5x2.0mm 6-SMD.

Other DSC1121 order codes with the same 6-SMD package and supply voltage range are pin-compatible — the difference is frequency, stability, or temperature range.
