Maximum supply current is 35 mA, with a disabled-mode draw of 22 mA — the enable/disable pin lets the system power down the oscillator when the clock tree is idle. No pin-compatible second source is listed, but the DSC1121 family includes multiple frequency and stability variants sharing the same 6-SMD footprint.","metaTitle":"DSC1121CM1-012.0000 MEMS Oscillator - Microchip - 12 MHz","metaDescription":"DSC1121CM1-012.0000: 12 MHz MEMS XO, CMOS output, 2.25-3.6V supply, -55 to 125°C.
