This multi-frequency capability means a single oscillator can serve a PCIe reference, a SerDes core, and a system clock without separate cans — a real BOM consolidation for a switch or router line card. ## Supply and output compatibility HCSL output (High-Speed Current Steering Logic) is the standard for PCIe and 100/1000BASE-T clock distribution; the 60 mA typical supply current covers the output swing into a 50-Ω terminated line. Not extended to industrial or automotive ambient; if the board sits in an unventilated enclosure above 70°C, this part drifts outside its stability spec. Housed in a 14-VFQFN with exposed pad (3.20 mm x 2.50 mm, 0.90 mm height).","metaTitle":"DSC2044FE1-F0024T MEMS XO – HCSL, 5 Frequencies, Active","metaDescription":"Microchip DSC2044FE1-F0024T MEMS XO, HCSL output, 50/100/125/156.25/200 MHz.
