Frequency stability is ±50 ppm across the -20 to 70°C industrial temperature range, sufficient for most 1 GbE, PCIe Gen 1/2, and FPGA reference clock jitter budgets. The 20-VFQFN exposed-pad package (5.00 x 3.20 mm, 0.90 mm height) requires a thermal via array under the pad for proper heat sinking — the MEMS die and output drivers dissipate through the exposed metal, so the board layout directly affects long-term frequency accuracy. ## Supply voltage and enable flexibility Operates from a single 2.25 V to 3.6 V supply, covering 2.5 V and 3.3 V logic rails without an external regulator — the wide input tolerance simplifies power-tree design when the oscillator shares a rail with the FPGA or ASIC bank. New designs can proceed without a last-time-buy contingency.","metaTitle":"DSC400-1111Q0084KE1T MEMS XO – 4-Output LVCMOS Clock","metaDescription":"Microchip DSC400-1111Q0084KE1T MEMS XO: 33.3333/50/125/100 MHz, LVCMOS, ±50 ppm, -20 to 70°C, 20-VFQFN.
