The 100 MHz lanes serve high-speed interfaces like PCIe or SerDes reference clocks; the 25 MHz lane typically feeds an Ethernet PHY or a low-speed controller. Outputs are configurable as HCSL or LVCMOS, so the same part can drive a differential clock bus (HCSL) or single-ended logic (LVCMOS) without a level translator. ## Supply voltage tolerance and temperature grade Rated for 2.25 V to 3.6 V supply, the oscillator runs directly off a 2.5 V or 3.3 V rail without an intermediate LDO.","metaTitle":"DSC400-1444Q0060KE1 MEMS XO – 100 MHz & 25 MHz Quad Output","metaDescription":"Active Microchip DSC400 MEMS oscillator, 4 outputs (3×100 MHz, 1×25 MHz), HCSL/LVCMOS, ±50 ppm, -20°C–70°C, 20-VFQFN.
