The DSC1121BI1-062.5000: AEC-Q100 qualification (Grade 3, 85°C ambient) makes this oscillator suitable for automotive electronics — under-hood or cabin modules that see temperature cycling and vibration — without the reliability screening burden of a custom crystal.
Operates from a 2.25V to 3.6V supply rail, covering common 2.5V and 3.3V logic domains without an external regulator.
Housed in a 6-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard 5×3.2 mm footprint that matches many quartz XO layouts, simplifying a drop-in replacement for designs migrating from crystal to MEMS. Surface-mount assembly with no through-hole leads; the 6-pad layout includes a center ground pad for thermal and electrical grounding. The MEMS resonator is inherently shock- and vibration-tolerant compared to a quartz blank, reducing failure risk in high-vibration environments like engine-mounted ECUs.
