A single 2.25 V to 3.6 V supply rail powers all four outputs, so the oscillator can run from a 2.5 V or 3.3 V plane without an intermediate regulator. ## Supply range and output type for clock tree planning The wide 2.25 V to 3.6 V supply range means the DSC400-2222Q0105KI1 operates across both 2.5 V and 3.3 V logic families without a dedicated voltage rail — the Enable/Disable function lets the system gate the outputs for power sequencing or test modes. LVPECL outputs provide low-jitter differential signalling for high-speed SerDes, Ethernet PHY reference clocks, and FPGA transceiver banks — the 200 MHz top output directly clocks a 10 GbE MAC or a Xilinx GTH quad. Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height), the DSC400-2222Q0105KI1 requires a thermal via array under the centre pad for heat sinking — the exposed pad must be soldered to a ground plane to keep the MEMS die within the -40 °C to 85 °C operating range.","metaTitle":"DSC400-2222Q0105KI1 MEMS XO, LVPECL, 4 Outputs 100-200 MHz","metaDescription":"Microchip DSC400-2222Q0105KI1 MEMS XO, LVPECL output, 4 fixed frequencies: 200, 156.25, 125, 100 MHz. -40 to 85°C, 2.25-3.6V supply.
