It is AEC-Q100 qualified, meaning it has passed the temperature, reliability, and PPAP requirements for automotive deployment — under-hood or cabin domain. The standby (power-down) pin drops the supply current from 8.7 mA max to 15 µA max — a 580:1 ratio that lets the oscillator sleep between bus wake cycles without draining the battery. A MEMS oscillator survives higher shock and vibration — typically 50,000 g vs 5,000 g for a quartz can — and has no crystal aging drift from the first year. The 4-SMD package has no exposed crystal can, so reflow is straightforward: standard lead-free profile, no special bake unless the reel moisture indicator card shows exposure.","metaTitle":"DSC1001DI2-074.2500T MEMS XO – 74.25 MHz, AEC-Q100","metaDescription":"Microchip DSC1001DI2-074.2500T – 74.25 MHz MEMS oscillator, XO type, CMOS output, ±25 ppm stability, AEC-Q100 qualified, -40°C to 85°C.
