LMK00301: can pcie 3.0/4.0 spread spectrum be supported?

hello_ao
Prodigy 100 points
Part Number: LMK00301

The datasheet shows that LMK00301 can be used for PCI Express (PCIe 3.0, 4.0),I wonder if it can support pice spread spectrum？

How much additive jitter with HCSL level at 100MHZ and156.25 MHz?

    The LMK00301 can accept a PCIe Gen3/4 input clock source with SSC modulation on it, and the SSC modulation will pass-through to its outputs with NO change to the SSC modulation (since this device does not have a PLL).

    The additive jitter for HCSL output at 100 MHz and 156.25 MHz are given in the datasheet electrical spec tables on page 11.
