That replaces three discrete crystal oscillators on the BOM, saving board area and reducing procurement line items. ## Timing budget and temperature grade For a 100 MHz Ethernet MAC reference, that stability keeps the link within the ±100 ppm total tolerance budget with margin for the PHY's own ppm contribution. The 2.25 V to 3.6 V supply range covers 2.5 V and 3.3 V rails without an external regulator—one less component on the power tree. 5.00 mm × 3.20 mm body, 0.90 mm height—the 20-VFQFN exposed pad requires a thermal via array under the paddle for heat sinking. The DSC400 series is the current product family; no successor has been announced.","metaTitle":"DSC400-0111Q0117KE1T MEMS XO – 4-Output LVCMOS Oscillator","metaDescription":"Active MEMS XO from Microchip, 4 outputs (16.64/33/25 MHz), ±50 ppm, LVCMOS, Enable/Disable, 20-VFQFN.
