That replaces up to six discrete XOs on the board, saving real estate and BOM line count. ## Active production — no EOL clock ticking Microchip lists this part as Active. For a production line that needs multi-year supply, this is a clean bill of health. ## Supply voltage tolerance and temperature grade Runs from 2.25 V to 3.6 V, so it sits on a 2.5 V or 3.3 V rail without a separate regulator. The 20-VFQFN Exposed Pad package (5.00 mm × 3.20 mm, 0.90 mm height) needs a thermal pad on the PCB for heat sinking. The exposed paddle also ties to the ground plane, which helps with EMI containment on the output traces.","metaTitle":"DSC400-1111Q0019KI2T MEMS XO – 6 Freq, LVCMOS, Active","metaDescription":"Microchip DSC400-1111Q0019KI2T MEMS XO: 25/50/125/150/100/156.25 MHz, LVCMOS, ±25 ppm, Enable/Disable, -40°C~85°C, 20-VFQFN.
