Outputs are configurable as HCSL or LVDS, covering common reference clock requirements for Ethernet PHYs, PCIe, and FPGA transceivers without needing a separate fanout buffer. Supply voltage spans 2.25 V to 3.6 V, so the same part can run from a 2.5 V or 3.3 V rail without a regulator change. The 20-VFQFN exposed-pad package (5.00 mm x 3.20 mm, 0.90 mm height) requires a thermal via pattern under the pad for proper heat transfer — the datasheet's recommended land pattern is worth following for reliable solder-joint life.","metaTitle":"DSC400-4334Q0023KI1 MEMS XO – 100 MHz & 156.25 MHz","metaDescription":"Microchip DSC400-4334Q0023KI1 dual-output MEMS XO: 100 MHz & 156.25 MHz, HCSL/LVDS, 2.25-3.6 V, ±50 ppm, -40 to 85 °C.
