That replaces up to four discrete XOs with one device, cutting placement cost and board area on multi-rail timing trees for Ethernet switches, PCIe reference clocks, and FPGA multi-clock designs. ## Supply tolerance and output compatibility Runs from 2.25 V to 3.6 V — the same BOM rail serves 2.5 V and 3.3 V systems without a separate regulator. The mixed HCSL/LVCMOS output stage means the 156.25 MHz lane can drive a differential HCSL clock tree (common on PCIe Gen 1–3) while the three 25 MHz lanes stay single-ended for the system controller and PHY. ## Industrial temperature and frequency hold For an outdoor small-cell backhaul or a factory-floor PLC clock, this keeps the Ethernet link from dropping when the enclosure hits 70°C. Microchip lists this as Active.","metaTitle":"DSC400-4111Q0112KI1T MEMS XO – 4-Output, HCSL/LVCMOS, Active","metaDescription":"Microchip DSC400-4111Q0112KI1T MEMS oscillator: 4 outputs (25MHz x3, 100/156.25MHz), HCSL/LVCMOS, ±50ppm, -40°C~85°C.
