Typical supply current is 60mA max with both outputs active; disabling the outputs drops consumption to 23mA max — useful for battery-backed systems that gate the clock during sleep. Housed in a 14-VFQFN with exposed pad, measuring 3.20mm x 2.50mm with a 0.90mm seated height.","metaTitle":"DSC2044FI2-F0012 MEMS XO Oscillator – Microchip, 100/125MHz","metaDescription":"Active production MEMS oscillator from Microchip.
