The DSC1121AM2-016.0000 carries AEC-Q100 qualification — the automotive IC stress and reliability standard. The OEM auditor expects PPAP documentation on this line; the part is production-validated for under-hood or cabin deployments where the ambient temperature profile spans -55°C to +125°C. This is not an industrial part dressed as 'automotive-capable' — the AEC-Q100 rating is explicit on the datasheet, meaning the part passed the full suite of pre- and post-stress electrical tests per the grade defined by the supplier.
MEMS resonator and output drive
The CMOS output drives directly into standard logic inputs without an external level translator. Supply voltage spans 2.25 V to 3.6 V — the same oscillator works across a 3.3 V main rail and a 2.5 V I/O bank without a separate clock divider or level-shifter.
Design-in is supported; second-source or pin-compatible alternatives are not documented in the DSC1121 family. The 6-SMD, No Lead Exposed Pad package (7.00 mm x 5.00 mm footprint) is the standard 7×5 mm oscillator land pattern.
