Quad-frequency MEMS oscillator for clock-tree consolidation
The DSC400-1122Q0036KE1 is a MEMS-based XO oscillator that delivers four independent output frequencies from a single 20-VFQFN package: 100 MHz, 156.25 MHz, 25 MHz, and 50 MHz. It replaces up to four discrete quartz oscillators on the board, saving footprint and reducing BOM line count — useful when a switch/router or FPGA clock tree needs multiple reference clocks. Outputs are configurable as LVCMOS or LVPECL, so the same part can feed a standard logic input or a differential clock receiver without a translator.
Operates from 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V logic rails — no extra regulator needed when the board has both supplies.
