Microchip lists the DSC400-2222Q0118KE2T as active (current production). ## 20-VFQFN with exposed pad: layout notes Housed in a 5.00 mm × 3.20 mm, 20-lead VFQFN with an exposed pad (0.90 mm height).","metaTitle":"DSC400-2222Q0118KE2T MEMS XO – 100MHz/125MHz LVPECL Quad","metaDescription":"Microchip DSC400-2222Q0118KE2T quad-output MEMS XO: 100MHz/125MHz LVPECL, ±25ppm, 2.25-3.6V, 20-VFQFN.
