The wide supply range of 2.25V to 3.6V covers 2.5V and 3.3V rails directly, eliminating a dedicated LDO for the oscillator supply. ## Stability and temperature grade The -20°C lower limit means this part is not rated for cold-start automotive or outdoor telecom cabinet use; those applications need the industrial-temperature variant of the DSC400 family. ## Package and board layout notes The 20-VFQFN with exposed pad (5.00mm x 3.20mm body, 0.90mm height) requires a thermal via array under the pad for proper heat transfer; the datasheet layout recommendation should be followed to keep junction temperature within limits. ## Lifecycle and sourcing status","metaTitle":"DSC400-0401Q0103KE2 MEMS XO – 12.288MHz & 100MHz, ±25ppm","metaDescription":"Microchip DSC400-0401Q0103KE2: MEMS-based XO, dual output HCSL/LVCMOS, 12.288MHz & 100MHz, ±25ppm, 2.25V-3.6V, -20°C to 70°C.
