MEMS oscillator for harsh-environment timing
The DSC1121BM1-050.0000T: AEC-Q100 qualification confirms the part meets automotive-grade reliability stress and PPAP requirements, answering the question of automotive suitability directly.
Supply voltage and frequency stability
Frequency stability is ±50 ppm, tight enough for 10/100 Ethernet and most MCU clock trees; the MEMS resonator's inherent shock resistance keeps the output within spec under 50 g vibration, unlike quartz which can exhibit micro-jumps.
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 matches industry-standard 5x3.2 mm oscillator pads — a drop-in replacement for quartz oscillators in the same form factor, provided the supply and output type align.
