The DSC2044FI2-F0022 delivers two 100 MHz HCSL outputs from a single MEMS resonator — a direct fit for PCIe reference clocks that need a clean 100 MHz source without an external crystal or PLL. HCSL (High-Speed Current Steering Logic) swings into a terminated differential pair, matching the input requirements of most PCIe clock receivers without level translation.
