The MEMS resonator base provides inherent shock and vibration resistance compared to quartz-based oscillators, reducing failure risk in high-vibration environments like factory floors or vehicle powertrains. ## Standby mode and power budget for battery-backed designs A standby (power-down) function on pin 1 drops the supply current to 15 µA max when disabled, while active operation draws 6.3 mA max – a 400× reduction that matters for always-on systems like automotive body controllers or IoT sensors that sleep between wake events. The wide supply range of 1.8V to 3.3V allows the oscillator to share a rail with a 1.8V MCU core or a 3.3V peripheral bus without an extra regulator, simplifying the power tree. Housed in a 5.0 mm × 3.2 mm 4-SMD no-lead package (0.90 mm seated height), the DSC1001BI2-026.9730T fits standard oscillator footprints and is supplied on tape and reel for automated assembly.","metaTitle":"DSC1001BI2-026.9730T – Microchip 26.973 MHz MEMS XO","metaDescription":"Microchip DSC1001BI2-026.9730T: 26.973 MHz MEMS oscillator, CMOS output, ±25 ppm stability, AEC-Q100, standby mode.
