The Enable/Disable function lets the system designer gate the clock output without removing power — useful for power-sequencing or test modes where the downstream logic must be held in reset. ## Supply voltage flexibility and current draw Operating from 2.25V to 3.6V, this oscillator spans the common 2.5V and 3.3V logic rails without an external LDO — a single supply covers both, simplifying the power tree. Maximum supply current is 35 mA when enabled; disabling the output drops the draw to 22 mA max, which matters for battery-backed or always-on modules where every milliamp counts. Housed in a 6-SMD no-lead package measuring 7.00mm x 5.00mm with a seated height of just 0.90mm, this oscillator fits standard clock footprints and reflow profiles common to automotive PCBs. No end-of-life notice or successor has been announced.","metaTitle":"DSC1121NI2-125.0000T MEMS Oscillator 125 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121NI2-125.0000T XO (Standard) MEMS oscillator, 125 MHz CMOS output, ±25 ppm stability, AEC-Q100, -40°C to 85°C, 6-SMD.
