The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal — a meaningful advantage in motor-drive or powertrain environments where crystal micro-cracking is a known failure mode. ## Supply voltage and output drive Operating from 2.25V to 3.6V, this oscillator spans the 2.5V and 3.3V logic rails common in automotive ECUs and industrial controllers — no extra regulator needed for the clock tree. Maximum supply current is 35 mA; the disable function drops it to 22 mA — useful for power-save modes in battery-backed or ignition-off domains. Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, it fits tight-profile designs and standard reflow processes. The Enable/Disable pin lets a GPIO or power-management IC gate the output — no external load-switch or series FET needed to silence the clock during sleep. This part is suitable for new designs and production builds without a forced migration timeline.","metaTitle":"DSC1121CI2-012.2880T MEMS XO – 12.288 MHz, AEC-Q100","metaDescription":"Microchip DSC1121CI2-012.2880T: MEMS-based XO, 12.288 MHz, CMOS output, ±25 ppm stability, -40°C to 85°C, AEC-Q100 qualified.
