Four output frequencies are pre-programmed: 125 MHz, two 100 MHz lanes, and a 50 MHz lane — all via LVDS signalling, making it a single-device clock source for multi-rail systems like FPGA transceiver banks or switch fabric reference clocks. Supply voltage spans 2.25 V to 3.6 V, so it can run from a 2.5 V or 3.3 V rail without an external LDO; the Enable/Disable function on the 20-VFQFN package lets a host controller gate the outputs for system power sequencing. ## MEMS reliability vs quartz – no cold-start drift MEMS resonator technology eliminates the quartz crystal's frequency warm-up drift — the part is stable at ±50 ppm immediately after power-on, which matters for industrial Ethernet or base station timing that must lock within milliseconds of a cold boot. The 20-VFQFN exposed-pad package (5.00 mm x 3.20 mm, 0.90 mm height) is a standard footprint for MEMS oscillators — board layout is straightforward, and the exposed pad provides a thermal path to the PCB ground plane for heat sinking.","metaTitle":"DSC400-3333Q0094KI1T MEMS XO – 125 MHz LVDS","metaDescription":"Active MEMS-based XO, 125 MHz LVDS output, ±50 ppm stability, -40°C to +85°C, 20-VFQFN.
