MEMS timing for automotive duty
Supply and stability margins
Operating from 2.5 V to 3.3 V with ±50 ppm frequency stability, this oscillator maintains timing accuracy across the full voltage and temperature range — eliminating the need for a separate LDO to supply a cleaner rail. The 27 mA typical supply current is consistent with a standard CMOS output buffer driving a moderate capacitive load.
Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, the DSC1221DI1-21M11840T fits into space-constrained designs such as automotive camera modules or compact telematics control units.
