The DSC1121BE5-025.0000T is a 25 MHz MEMS-based oscillator from Microchip's DSC1121 series, delivering CMOS output with ±10 ppm frequency stability across its -20°C to 70°C operating range. Rated AEC-Q100, this part carries the automotive-grade qualification that industrial-grade XO oscillators lack — the OEM auditor will ask for PPAP documentation, and the AEC-Q100 stamp confirms the part was screened to the temperature, reliability, and stress tests required for under-hood or cabin electronics.
A 2.25V to 3.6V supply range covers both 2.5V and 3.3V rails directly — no extra regulator needed for the oscillator, which simplifies the power tree and frees up board space.
Housed in a 6-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — the footprint is standard for MEMS oscillators of this class and matches the industry-common 5.0 x 3.2 mm land pattern. Surface-mount assembly with a 0.197" x 0.126" body — the low profile and small footprint suit space-constrained automotive control modules and sensor nodes.
