The wide supply voltage range of 2.25V to 3.6V lets this oscillator run directly from a 2.5V or 3.3V rail without an extra LDO, simplifying the power tree. Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. The exposed pad provides a low-thermal-resistance path to the PCB — ensure the pad is soldered to a copper plane for best heat dissipation, especially in high-ambient-temperature automotive environments. ## Enable/Disable function for power savings This is useful for battery-powered or intermittently operated systems where the clock can be gated to save power when the downstream logic is idle.","metaTitle":"DSC1121AI5-010.0000 MEMS Oscillator 10 MHz ±10 ppm AEC-Q100","metaDescription":"Microchip DSC1121AI5-010.0000 XO (Standard) 10 MHz CMOS output MEMS oscillator.

MEMS oscillators are inherently more resistant to shock, vibration, and temperature cycling — a key advantage in automotive and industrial environments where quartz crystals can experience frequency drift or failure. The ±10 ppm stability is comparable to a good quartz oscillator, but the MEMS part does not require external load capacitors or a separate crystal."},{"question":"Is the DSC1121AI5-010.0000 AEC-Q100 qualified?","answer":"Yes, it carries AEC-Q100 ratings, meaning it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up.
