It is AEC-Q100 qualified, meaning it has passed the automotive-grade reliability stress and temperature cycling tests required for under-hood or cabin electronics. The supply voltage range spans 1.8V to 3.3V, letting the same oscillator serve 1.8V core logic and 3.3V I/O domains without a separate level translator. ## Standby function and power-down current A standby (power-down) pin disables the output and drops the supply current to 15 µA max, making this oscillator suitable for battery-backed modules that sleep between wake cycles. When active, the maximum supply current is 7.2 mA at 40 MHz — the MEMS core draws less than a comparable quartz crystal oscillator at the same frequency. ## Temperature range and frequency stability Frequency stability is ±10 ppm across the full temperature range, tight enough for CAN FD, Ethernet, and most serial bus reference clocks.","metaTitle":"DSC1001BL5-040.0000T – 40 MHz MEMS XO, AEC-Q100, 1.8-3.3V","metaDescription":"Microchip DSC1001BL5-040.0000T: 40 MHz MEMS XO, CMOS output, AEC-Q100 qualified, 1.8-3.3V supply, standby function.
