Supply voltage spans 1.7V to 3.6V, so it runs from a 1.8V core rail or a 3.3V I/O rail without an extra LDO. The 6 mA max supply current at 20 MHz is low enough that a small 100 nF decoupling cap at the Vdd pin is sufficient — no bulk electrolytic needed. ## Standby power-down for battery-backed designs That is the difference between a coin cell lasting a month versus a year in a remote sensor that sleeps most of the time. ## AEC-Q100 qualification and active production It is suitable for under-hood, cabin, or chassis-domain ECUs where the ambient temperature hits 85°C and the board sees vibration. Product status is Active.","metaTitle":"DSC1003CI5-020.0000 XO 20 MHz CMOS MEMS Oscillator","metaDescription":"Active-production MEMS XO, 20.0000 MHz, CMOS output, AEC-Q100 qualified, -40°C to +85°C, 1.7V–3.6V supply.
