Unlike a quartz crystal that needs external load capacitors and an inverter, this is a complete oscillator in a 4-SMD no-lead package — drop it on the board, connect 1.8V to 3.3V, and it clocks. ## AEC-Q100 qualification and the temperature envelope ## Power budget and standby behaviour Drawing a maximum of 6.3 mA when active, the DSC1001CL2-012.0000T is efficient enough for a battery-backed module; in standby (power-down) the current drops to 15 µA max, letting the system sleep the clock tree without a separate gating FET. The standby function is a logic-level pin — pull it low and the output stops, the core goes to sleep, and the supply current falls to the microamp range. No external enable circuit needed. ## Supply voltage flexibility The wide 1.8V to 3.3V supply range means the same oscillator works across a 1.8V MCU, a 2.5V FPGA bank, or a 3.3V peripheral bus — no level translator or separate LDO for the clock source.","metaTitle":"DSC1001CL2-012.0000T MEMS Oscillator – 12 MHz, AEC-Q100","metaDescription":"DSC1001CL2-012.0000T: Microchip MEMS XO, 12 MHz CMOS output, ±25 ppm stability, 1.8V–3.3V supply, AEC-Q100 qualified.
