Output logic is configurable as HCSL, LVCMOS, or LVDS, giving the system architect flexibility to drive a mix of clock domains — for example, a 100 MHz LVDS reference to an FPGA and a 25 MHz LVCMOS clock to a PHY — without extra level translation. ## Supply range and enable/disable function Operates from a 2.25 V to 3.6 V supply, covering the common 2.5 V and 3.3 V logic rails without a separate regulator. Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm body, 0.90 mm height), the package footprint is compact enough for space-constrained PCIe cards or small-form-factor networking modules.","metaTitle":"DSC400-4134Q0028KE1 Datasheet, Price & Stock","metaDescription":"DSC400-4134Q0028KE1 MEMS XO, 4 outputs 100/125/25/100 MHz, ±50 ppm, -20°C~70°C, 20-VFQFN.
