That span covers avionics cold-soak, downhole tool heat, and engine-bay ambient where a standard -40°C to 85°C part would drift out of spec or stop oscillating. AEC-Q100 qualification means the device has passed the reliability stress and PPAP requirements for automotive deployment — under-hood or cabin-domain ECUs can use it without a separate qual run. ## Supply voltage and output compatibility With a 2.25V–3.6V supply range and CMOS output, this oscillator interfaces directly with 2.5V and 3.3V logic families — no level translation needed on the clock line. 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 no-lead construction means the terminations are flush with the package body — the PCB footprint must match the land pattern exactly; there are no protruding leads to absorb board flex.","metaTitle":"DSC1121BM1-008.0000T MEMS XO – Microchip, 8 MHz, CMOS","metaDescription":"Active-production MEMS oscillator from Microchip Technology. 8 MHz CMOS output, 2.25V–3.6V supply, -55°C to 125°C range, AEC-Q100 qualified.
