The 20-VFQFN exposed-pad package (5.00 mm x 3.20 mm, 0.90 mm height) requires a thermal pad on the PCB for proper heat dissipation and mechanical stability. Check the MSL before reflow — the exposed pad demands a solder paste stencil aperture that covers at least 50% of the pad area to avoid voids and tombstoning. No last-time-buy window or successor part has been announced.","metaTitle":"DSC400-1111Q0110KI1 MEMS XO – 4-Output LVCMOS Clock","metaDescription":"Active MEMS XO from Microchip DSC400 series.
