The ±50 ppm frequency stability holds the clock edge within a tight window across the -20°C to 70°C range, so a 40 MHz MCU PLL sees minimal jitter accumulation from the reference. Operates from a 1.8V to 3.3V supply rail — the same pin powers the oscillator core and the output buffer, so the logic family of the downstream device sets the VDD choice. Active current draw is 7.2 mA max at 40 MHz — low enough that the 4-SMD package's thermal path handles the dissipation without a heatsink. Housed in a 5.00 mm x 3.20 mm 4-SMD no-lead package with a seated height of 0.90 mm max — the footprint matches industry-standard 5.0 x 3.2 mm XO land patterns, so a layout designed for a quartz oscillator in the same form factor accepts this MEMS part without a board spin.","metaTitle":"DSC1001BE1-040.0000T MEMS XO, 40 MHz, CMOS, AEC-Q100, Active","metaDescription":"Microchip DSC1001BE1-040.0000T: MEMS-based XO, 40 MHz, CMOS output, ±50 ppm stability, AEC-Q100, -20°C to 70°C.
