The wide 2.25V to 3.6V supply range means the same BOM line works across a 2.5V or 3.3V rail without a separate regulator — useful when the clock tree spans multiple voltage domains. ## Active lifecycle and package footprint Housed in a 20-VFQFN with exposed pad (5.00mm x 3.20mm, 0.90mm height), the package requires a thermal via pattern under the pad for heat sinking — the datasheet's recommended land pattern should be followed to keep the junction temperature within the -40°C to 85°C operating range.","metaTitle":"DSC400-3333Q0078KI2 MEMS XO – Quad 125 MHz LVDS, ±25 ppm","metaDescription":"Microchip DSC400-3333Q0078KI2: quad-output 125 MHz LVDS MEMS oscillator, ±25 ppm stability, 2.25V–3.6V supply, industrial temp.
