Supply voltage spans 2.25 V to 3.6 V — a single 2.5 V or 3.3 V rail powers all four lanes, simplifying the power distribution on a mixed-voltage board. Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height), the package demands a thermal via array under the pad for heat sinking — the MEMS die dissipates little heat, but the pad still needs a solid ground-plane connection for EMI containment.","metaTitle":"DSC400-3333Q0078KI1 MEMS Oscillator – 4x 125MHz LVDS, Active","metaDescription":"DSC400-3333Q0078KI1 – XO (Standard) MEMS oscillator, 4x 125 MHz LVDS outputs, ±50ppm stability, -40°C~85°C, 20-VFQFN.
