Why a MEMS XO with AEC-Q100 matters on your BOM
The DSC1001CI1-005.0000T is a MEMS-based oscillator, not a quartz can — the silicon resonator doesn't suffer from the cold-start frequency shift or vibration sensitivity that can pull a quartz part out of spec in an automotive or industrial enclosure. The 1.8V to 3.3V supply range means this single order code can serve a 1.8V MCU core clock, a 2.5V FPGA reference, or a 3.3V peripheral bus without a separate voltage rail — one line item, three voltage domains.
Parametric fit: 5 MHz CMOS with standby control
Housed in a 4-VDFN package measuring 3.20 mm x 2.50 mm x 0.90 mm — the same footprint as many standard quartz oscillators, so it drops onto existing PCB layouts without a board spin.
