Frequency stability is ±10 ppm over the operating range — tight enough for 100BASE-T1 or CAN FD bit-timing budgets where a ±25 ppm quartz part would eat into the jitter margin at the receiver. Supply voltage spans 1.8V to 3.3V, so the same order code serves a 1.8V MCU core clock and a 3.3V peripheral bus without a second oscillator variant on the BOM. ## Standby mode and power-down current – 15 µA max","metaTitle":"DSC1001BE5-044.0000T MEMS Oscillator – 44 MHz, AEC-Q100","metaDescription":"Microchip DSC1001BE5-044.0000T – 44 MHz XO (Standard), CMOS output, AEC-Q100, ±10 ppm stability, 1.8V–3.3V supply.
