The output is a clean CMOS clock at 24 MHz, ±10 ppm stability across -40°C to 85°C, which holds the frequency tighter than a basic quartz oscillator over temperature. The supply voltage spans 2.25V to 3.6V, so the same part works on a 2.5V FPGA bank or a 3.3V MCU rail without a level translator. Enable/Disable function lets the system gate the clock when the peripheral is idle — the disable current drops to 22 mA max from the 35 mA max running draw. ## Active production — no LTB window to watch Microchip lists the DSC1121BI5-024.0000T as Active. For a BOM that needs a stable 24 MHz reference, this part is available for new designs and production builds — no forced redesign horizon. ## Package and temperature grade for field-fit Housed in a 6-VDFN package, 5.00 mm x 3.20 mm with a seated height of 0.90 mm. Surface-mount footprint is standard — no special via-in-pad or buried-via requirements.","metaTitle":"DSC1121BI5-024.0000T MEMS XO 24 MHz CMOS ±10 ppm -40°C to","metaDescription":"Active Microchip DSC1121BI5-024.0000T: MEMS-based XO, 24 MHz, CMOS output, ±10 ppm stability, 2.25V–3.6V supply, -40°C to 85°C, 6-VDFN.
