This lets a single device replace two discrete oscillators in a 100 MHz reference plus 156.25 MHz SerDes clock application, saving board space and reducing BOM line count. Housed in a 20-VFQFN exposed-pad package measuring 5.00 mm × 3.20 mm with a 0.90 mm seated height, the device fits tight PCB layouts. Supply voltage range of 2.25 V to 3.6 V covers common 2.5 V and 3.3 V rails without an external regulator. ## Lifecycle and sourcing status","metaTitle":"DSC400-4334Q0023KE1 MEMS XO – 100 MHz / 156.25 MHz","metaDescription":"Microchip DSC400-4334Q0023KE1 dual-output MEMS XO: 100 MHz and 156.25 MHz, HCSL/LVDS, ±50 ppm, -20 to 70°C.
