Four 100 MHz HCSL outputs from a single MEMS resonator
HCSL (High-Speed Current Steering Logic) is the standard clock format for PCI Express reference clocks — the 100 MHz frequency matches the PCIe Gen 1/2/3 reference clock requirement, so this part can serve as the PCIe root-complex clock source.
The supply voltage range of 2.25V to 3.6V covers both 2.5V and 3.3V rails — no separate LDO is needed when the board uses either rail, and the part tolerates the ripple from a switching regulator as long as it stays within the absolute-maximum rating.
