The AEC-Q100 rating means it passed automotive-grade reliability stress: -20°C to 70°C operating range is the commercial band, so this part suits cabin or infotainment modules where the ambient stays below 70°C, not an under-hood ECU that sees 105°C. The ±25 ppm frequency stability keeps the timing budget tight enough for 100BASE-TX without a separate PLL cleanup. ## Supply-rail flexibility and standby power The 1.8V to 3.3V supply range lets this oscillator drop into designs with a 1.8V core rail or a 3.3V I/O rail without a separate voltage translator. Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. Rework is straightforward with hot air: the pad is large enough that a standard 8mm nozzle covers it, and the four corner pads are easy to inspect. No lead means no bent pins to straighten — just align, reflow, and check for tombstoning on the corner pads.","metaTitle":"DSC1001AE2-012.2880 MEMS XO 12.288 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1001AE2-012.2880: MEMS XO, 12.288 MHz, CMOS output, ±25 ppm stability, AEC-Q100, 1.8-3.3V supply.
