Outputs are configurable as LVCMOS or LVDS — LVDS for differential clock distribution to high-speed SerDes or FPGA reference inputs, LVCMOS for single-ended logic families. ## 20-VFQFN package and board layout notes Housed in a VFQFN with exposed pad, 5.00 mm x 3.20 mm body, 0.90 mm height — the exposed paddle must be soldered to a ground-plane via array for thermal and electrical connection. The 0.90 mm profile fits under heatsinks or in tight card-edge clearance zones common in 1U rack-mount gear.","metaTitle":"DSC400-1133Q0079KE1T MEMS XO – 4-Output, LVCMOS/LVDS, Active","metaDescription":"Microchip DSC400-1133Q0079KE1T MEMS XO: 100/100/66.666/25 MHz outputs, LVCMOS/LVDS, ±50 ppm stability, -20°C to +70°C.
