The DSC1001DI2-008.0000T is a fixed-frequency 8 MHz XO (Standard) from Microchip's DSC1001 series, built on a MEMS resonator rather than a quartz crystal. The CMOS output and 1.8V to 3.3V supply range let it drop into most digital timing trees without a level translator. AEC-Q100 qualification means this part has passed the automotive-grade reliability stress suite — temperature cycling, ESD, latch-up — and is suitable for under-hood or cabin electronics where the ambient hits -40°C to 85°C.
Frequency stability and power budget for the BOM
Frequency stability is ±25 ppm — tight enough for a CAN bus or MCU clock where the total timing error budget across temperature and aging stays under 100 ppm. The max supply current is 6.3 mA; in standby (power-down) the disable current drops to 15 µA, which matters for battery-backed modules that sleep between wake cycles.
