It outputs a CMOS-level clock and includes an Enable/Disable function for power savings in multi-clock systems. Rated AEC-Q100, this oscillator is qualified for automotive temperature and reliability stress — suitable for under-hood or cabin electronics where a standard commercial oscillator would not carry the required PPAP documentation. ## Supply voltage, stability, and current draw The supply voltage spans 2.25 V to 3.6 V, covering 2.5 V, 3.0 V, and 3.3 V rails without a separate regulator. Frequency stability is ±25 ppm across the -20°C to +70°C operating range. Maximum supply current is 35 mA when enabled; disabling the output via the Enable/Disable pin drops the draw to 22 mA max — useful for battery-powered or thermal-sensitive designs that gate the clock in sleep modes. ## Package and board mounting Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. The exposed pad on the underside provides a thermal path to the PCB ground plane; the datasheet recommends a thermal-via pattern under the pad for heat spreading. Surface-mount assembly with standard reflow profiles; the MEMS die inside is less sensitive to mechanical shock than a quartz blank, so no special handling beyond normal SMD precautions is required. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1121AE2-020.0000T 20 MHz MEMS XO AEC-Q100","metaDescription":"DSC1121AE2-020.0000T: Microchip 20 MHz MEMS oscillator, CMOS output, ±25 ppm, AEC-Q100, 2.25-3.6V, 6-SMD.
