The 5.00mm x 3.20mm 20-VFQFN with exposed pad (0.90mm height) requires a thermal pad on the PCB for heat sinking. The 0.50mm pitch pads demand careful fan-out on a 4-layer board; two-layer designs can break out the outer rows but may struggle with signal integrity at 100 MHz.","metaTitle":"DSC400-1111Q0001KE2T MEMS XO – 100 MHz Quad LVCMOS, ±25 ppm","metaDescription":"Microchip DSC400-1111Q0001KE2T: MEMS XO, 4 outputs at 100 MHz LVCMOS, ±25 ppm stability, 2.25-3.6V supply, -20 to 70°C.
