The MEMS resonator eliminates quartz startup issues and vibration sensitivity, making it a solid fit for FPGA reference clocks, 10GbE SerDes, or any high-speed serial link where LVPECL levels are the standard. Supply voltage spans 2.5V to 3.3V, so it can run directly off a 3.3V rail or a 2.5V FPGA bank without an external regulator. The 6-VDFN package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits tight board layouts, though the 0.50 mm pitch demands careful PCB land pattern design and a stencil with good aperture-to-pad ratio for hand-solder or reflow. ## Active lifecycle — no obsolescence worry Microchip lists the DSC1222DI2-121M1090T as Active.","metaTitle":"DSC1222DI2-121M1090T MEMS XO – Microchip, 121.109 MHz","metaDescription":"Microchip DSC1222DI2-121M1090T: MEMS XO, 121.109 MHz, LVPECL output, ±25 ppm stability, -40 to 85°C, 6-VDFN.
