That replaces up to four discrete oscillators on the board, freeing layout space and reducing BOM line count. For a 125 MHz LVPECL clock, that keeps the edge placement within a few picoseconds of nominal over temperature. ## Supply flexibility and output control Supply voltage spans 2.25 V to 3.6 V, so it runs directly from a 2.5 V or 3.3 V rail without an intermediate regulator. LVPECL outputs deliver the differential swing needed for high-speed SerDes, FPGA reference clocks, or Ethernet PHY interfaces. The 0.90 mm height keeps it low-profile for mezzanine cards or blade servers where board-to-board clearance is tight. Microchip lists the DSC400-2222Q0104KI2T as Active.","metaTitle":"DSC400-2222Q0104KI2T Quad LVPECL MEMS Oscillator","metaDescription":"DSC400-2222Q0104KI2T: XO (Standard) MEMS oscillator, 4 LVPECL outputs (125/100/200/156.25 MHz), ±25 ppm stability, -40 to +85°C, 20-VFQFN.
