Maximum supply current is 35 mA when enabled; with the output disabled it drops to 22 mA max — not a deep-sleep level, but enough to save a few milliamps in a standby state.","metaTitle":"DSC1121CI2-045.1580 MEMS XO 45.158 MHz CMOS ±25 ppm","metaDescription":"Microchip DSC1121CI2-045.1580 MEMS oscillator, 45.158 MHz, CMOS output, ±25 ppm stability, -40°C to 85°C, 6-VDFN.
