Its MEMS resonator replaces the quartz crystal — expect faster startup and better resistance to shock and vibration compared to a traditional crystal oscillator. ## Automotive temperature range and qualification AEC-Q100 qualification means it has passed the automotive-grade reliability stress tests: temperature cycling, ESD, and latch-up immunity per the standard. ## Enable/Disable function and supply current The Enable/Disable pin lets you gate the output — useful for power sequencing or test modes. When disabled, the supply current drops to 22 mA max from the 35 mA max active draw. Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm x 0.90mm, it fits a standard oscillator footprint — no special layout changes needed for a drop-in replacement.","metaTitle":"DSC1121AM1-050.0000T – 50 MHz CMOS XO, AEC-Q100, Active","metaDescription":"Microchip DSC1121AM1-050.0000T: 50 MHz XO (Standard), CMOS output, ±50 ppm stability, -55°C to 125°C, AEC-Q100.
