Output 1 is configurable as HCSL or LVPECL, covering PCIe reference-clock and SerDes PLL applications; output 2 provides a lower-speed clock for a management interface or auxiliary logic. ## Wide supply range and disable function for power budgeting Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails commonly found in networking and FPGA boards—no extra regulator needed for the oscillator rail. At 76 mA typ with both outputs active, the current draw is dominated by the 156.25 MHz HCSL driver—budget this into the 3.3 V rail capacity for the clock tree. ## 14-VFQFN package – layout and thermal pad","metaTitle":"DSC2042FI2-M0005 MEMS Oscillator – 156.25 MHz / 25 MHz","metaDescription":"Microchip DSC2042FI2-M0005 dual-output MEMS XO: 156.25 MHz HCSL/LVPECL + 25 MHz, ±25 ppm, -40°C to 85°C, 14-VFQFN.
