Each output can be independently configured as HCSL, LVCMOS, or LVDS, letting one oscillator serve PCIe reference clocks, FPGA core clocks, and lower-speed serial interfaces from the same device. ## Supply voltage tolerance and enable/disable control The 2.25 V to 3.6 V supply range covers 2.5 V and 3.3 V rails without a separate LDO — useful when the same BOM must work across multiple voltage domains.","metaTitle":"DSC400-4134Q0028KE1T MEMS XO – Quad Output 100/125/25/100","metaDescription":"Active-production quad-output MEMS oscillator. 100, 125, 25, 100 MHz.
