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. ## Package and board layout note Housed in a 20-VFQFN with exposed pad, 5.00 mm x 3.20 mm footprint, 0.90 mm height.","metaTitle":"DSC400-1122Q0036KE1 XO Oscillator – Microchip MEMS","metaDescription":"Active XO oscillator from Microchip, MEMS-based, quad output: 100 MHz, 156.25 MHz, 25 MHz, 50 MHz.
