Four LVPECL clocks from one MEMS die
The DSC400-2222Q0118KE2 packs four LVPECL output pairs into a single 20-VFQFN package, each pair delivering 100 MHz or 125 MHz — all four outputs are identical in frequency and format. That means one oscillator replaces up to four discrete XOs on the clock tree, saving board area and reducing the number of supply bypass caps on the layout.
Rated for 2.25 V to 3.6 V supply, it sits comfortably on a 2.5 V or 3.3 V rail without an intermediate regulator.
Active lifecycle, no obsolescence pressure
Microchip lists the DSC400-2222Q0118KE2 as Active. No NRND flag, no last-time-buy window.
