The MEMS resonator inherently resists vibration-induced phase noise better than a bulk quartz blank, which matters for engine-bay or chassis-mounted electronics where the board sees constant mechanical stress. ## Supply rail flexibility and power budget The 2.25V to 3.6V supply range lets this oscillator drop into 2.5V, 3.0V, or 3.3V domains without a separate level translator — the internal LDO regulates the MEMS core from whichever rail is present. That 13 mA saving per clock tree matters in a multi-oscillator design where the total disable current stays under a single linear regulator's quiescent budget. Housed in a 6-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, this oscillator fits the standard 3.2 x 2.5 mm land pattern common to MEMS and quartz oscillators. The surface-mount, no-lead construction eliminates the solder-joint fatigue failure mode seen in gull-wing packages under thermal cycling — a relevant point for AEC-Q100 Grade 1 applications at 105°C. The Enable/Disable pin is active-low; tying it to Vdd keeps the output running, while pulling it low tristates the output and reduces current draw to the disable figure.","metaTitle":"DSC1121CL2-024.7500T MEMS XO, 24.75 MHz, AEC-Q100","metaDescription":"Microchip DSC1121CL2-024.7500T: MEMS-based XO, 24.75 MHz, ±25 ppm stability, CMOS, AEC-Q100, -40 to +105°C, 2.25-3.6V supply.
