The ±50 ppm frequency stability covers most Ethernet, PCIe, and FPGA reference-clock jitter budgets without needing an external VCXO. The exposed-pad QFN (5.00 mm x 3.20 mm, 0.90 mm height) requires a thermal via array under the pad for heat sinking; rework with hot air is feasible but the pad needs a clean stencil to avoid solder bridging on the perimeter leads.","metaTitle":"DSC400-2222Q0105KE1 – Microchip MEMS XO, LVPECL, 4 Outputs","metaDescription":"Active Microchip DSC400 MEMS XO, LVPECL output, ±50 ppm stability, 2.25–3.6 V supply, -20°C to 70°C, 20-VFQFN.
