Each output can be configured as HCSL or LVDS differential signaling, covering PCIe reference clocks and FPGA/SoC high-speed interfaces without an external level translator. ## What the ±50 ppm stability buys you Frequency stability of ±50 ppm over the -20°C to 70°C range keeps the clock edge jitter within the timing budget for 125 MHz PCIe Gen 1/2/3 reference clocks and 100 MHz Ethernet MAC/PHY interfaces. For tighter-precision applications (e.g., 10 GbE or SyncE), a ±25 ppm or ±10 ppm variant in the DSC400 family would be the better fit. The 0.90 mm package height fits standard mezzanine-card spacing and 1U rack-mount equipment where board-to-board clearance is tight.","metaTitle":"DSC400-4334Q0022KE1T MEMS Oscillator","metaDescription":"Microchip DSC400-4334Q0022KE1T quad-output MEMS XO: 125MHz & 100MHz HCSL/LVDS, ±50ppm, -20°C~70°C, 20-VFQFN.
