Max supply current is 95 µA, which means this oscillator adds under a tenth of a milliamp to the system power budget — relevant for battery-operated gateways, sensor nodes, or any always-on peripheral clock. ## Commercial temperature range and package Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, it takes up roughly the same board area as a small SOT-23 regulator, which helps when the layout is tight.","metaTitle":"DSC1101DE2-045.1584T MEMS XO 45.1584 MHz CMOS - Microchip","metaDescription":"Microchip DSC1101DE2-045.1584T MEMS oscillator, 45.1584 MHz, CMOS output, ±25ppm stability, 2.25-3.6V supply, 95µA max, standby function.
