This replaces the need for multiple crystal oscillators on a board, saving space and reducing BOM count. Operates from 2.25 V to 3.6 V, covering 2.5 V and 3.3 V FPGA/ASIC I/O rails without an external regulator. ## 20-VFQFN exposed pad — rework and layout notes The 20-VFQFN package (5.00 mm x 3.20 mm, 0.90 mm height) has an exposed pad that must be soldered to a thermal land on the PCB for heat sinking and mechanical stability. The pad is the only ground return for the die — a missing or poorly soldered pad can cause output jitter or intermittent failure. Rework tip: preheat the board to 125°C before hot-air removal to avoid lifting the pad. The part is moisture-sensitive — check the MSL label on the reel; if it has been exposed, a bake at 125°C for 48 hours is needed before reflow.","metaTitle":"DSC400-3333Q0041KI2T MEMS XO, LVDS, Quad Output, 20-VFQFN","metaDescription":"Microchip DSC400-3333Q0041KI2T MEMS XO (Standard) with LVDS output, quad frequencies up to 250 MHz, ±25ppm stability, -40°C to 85°C, 20-VFQFN.
