70.455 MHz MEMS oscillator with AEC-Q100 grade
The DSC1001CI5-070.4550: AEC-Q100 qualification means this part is validated for automotive-grade reliability — under-hood or cabin electronics that see thermal cycling, vibration, and long mission profiles can use it without additional screening. The MEMS resonator replaces a quartz crystal, giving better shock and vibration immunity and a faster start-up time compared to a traditional crystal oscillator — relevant for automotive camera modules or ADAS sensor clocks where the oscillator must lock quickly after a power-on reset.
Supply range and standby current
Operating from a 1.8V to 3.3V supply, this oscillator spans the common digital core and I/O rails — a single BOM line covers 1.8V, 2.5V, or 3.3V domains without a separate voltage translator. Standby (Power Down) function drops the supply current to 15 µA max when the enable pin is pulled low — useful for battery-backed modules that need to preserve the clock tree during sleep and wake on a timer or external event. Active supply current is 8.7 mA max at 70.455 MHz — the MEMS core draws less than a comparable quartz oscillator at this frequency, which matters for thermally constrained layouts in a sealed automotive ECU.
Housed in a no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the compact footprint fits into space-constrained designs. Surface-mount mounting with standard reflow profiles; the no-lead package has a flat bottom with solder pads on the underside, so the PCB land pattern should match the recommended footprint in the datasheet to avoid tombstoning during reflow.
