Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height), the DSC400 requires a thermal pad on the PCB for heat dissipation — the exposed pad should be soldered to a ground plane copper pour for optimal thermal and electrical performance. It remains a valid choice for new designs.","metaTitle":"DSC400-0401Q0103KE1T MEMS XO – 12.288 MHz & 100 MHz","metaDescription":"Microchip DSC400-0401Q0103KE1T: Active MEMS XO, dual outputs 12.288 MHz & 100 MHz, HCSL/LVCMOS, ±50 ppm, 2.25-3.6 V, 20-VFQFN.
