The supply voltage spans 2.25V to 3.6V, so it runs off a 2.5V or 3.3V rail without a separate LDO — one less part on the BOM. It fits indoor equipment, office peripherals, and consumer electronics — not an engine bay or outdoor base station. The absolute pull range (APR) is ±10ppm, which sets the frequency accuracy floor across temperature and aging. For a 45.1584 MHz clock, that is about ±452 Hz of total drift — tight enough for most UART and Ethernet PHY reference applications. ## Power-down standby and supply current Active supply current is 35mA max, typical for a 45 MHz CMOS output driving a 15 pF load. Budget this into the 3.3V rail — it is not a low-power oscillator, but the MEMS core keeps it well below a canned crystal oscillator's draw.","metaTitle":"DSC1101CE5-045.1584 Microchip MEMS XO 45.1584 MHz CMOS","metaDescription":"DSC1101CE5-045.1584: Microchip MEMS XO, 45.1584 MHz, CMOS output, 2.25-3.6V supply, -20 to 70°C, ±10ppm APR.
