MEMS oscillator for high-speed clock trees
Wide supply and industrial temperature range
That is enough for 1000BASE-T Ethernet and most PCIe reference clocks.
Draws 58 mA max while running — the LVPECL output stage is the main consumer, not the MEMS core. No external enable logic needed; the pin is already there.
Active lifecycle, no obsolescence worry
Listed as Active by Microchip. The DSC1102 family shares the same footprint across frequencies, so a BOM change to a different speed grade is a reel swap, not a board spin.
