The 20-VFQFN package with exposed pad is a standard reflow profile; no special moisture sensitivity handling beyond the MSL label on the reel.","metaTitle":"DSC400-4444Q0015KE1 MEMS XO – 4-Output HCSL Oscillator","metaDescription":"Microchip DSC400-4444Q0015KE1 quad-output XO: 25/50/125/150 MHz + 100/156.25 MHz HCSL, ±50 ppm, 2.25-3.6V, 20-VFQFN.
