Each output can be configured as HCSL, LVCMOS, or LVDS, letting one device feed a mixed-signal board with a PCIe reference, a SerDes clock, and a logic-level system clock. Operates from 2.25 V to 3.6 V, covering the common 2.5 V and 3.3 V FPGA/SoC rails without an external regulator. ## Package and board layout notes Housed in a 20-VFQFN with exposed pad, 5.00 mm × 3.20 mm body, 0.90 mm height.","metaTitle":"DSC400-4134Q0050KE1T MEMS XO – 4 Outputs, 100/125/50/100 MHz","metaDescription":"Microchip DSC400-4134Q0050KE1T XO (Standard), MEMS resonator, 4 outputs: 100MHz, 125MHz, 50MHz, 100MHz.
