Housed in a 5.00 mm x 3.20 mm, 0.90 mm tall 20-VFQFN with an exposed pad, the package requires a thermal via pattern under the pad for the datasheet-recommended RthJA — a standard 4-layer board with a solid ground plane under the pad is the baseline. Supplied in tape and reel, the DSC400-1444Q0060KE2T is compatible with automated pick-and-place and reflow assembly without special handling beyond standard MSL precautions.","metaTitle":"DSC400-1444Q0060KE2T MEMS XO – 4-Output, 100 MHz + 25 MHz","metaDescription":"Microchip DSC400-1444Q0060KE2T MEMS XO: 4 outputs (3x 100 MHz, 1x 25 MHz), HCSL/LVCMOS, ±25 ppm, 2.25-3.6 V, -20 to 70°C, 20-VFQFN.
