The 2.25 V to 3.6 V supply rail tolerance means the oscillator can share a 2.5 V or 3.3 V power plane without a dedicated LDO. The MEMS resonator technology avoids the quartz supply constraints and aging drift that can affect traditional crystal oscillators, making it a stable sourcing choice over the product lifecycle. Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height), the DSC400 requires a thermal pad on the PCB for both mechanical stability and heat sinking.","metaTitle":"DSC400-4334Q0022KE2T MEMS XO 125/100 MHz HCSL LVDS","metaDescription":"Microchip DSC400 quad-output MEMS oscillator, 125MHz & 100MHz, HCSL/LVDS, 2.25-3.6V, ±25ppm, Active.
