TUSB8041: Application questions

Part Number: TUSB8041

Hi Expert,

Does this device can support PCIe interface? if yes, what's the generation of PCIe? 

To check the DS, this device require external 24MHz crystal for design, if customer use 25MHz crystal, do you have any concern? or can we change 25MHz to 24MHz from internal FW setting?

    TUSB8041 is a USB3 hub, it can't support PCIe. 

    The crystal must be fundamental mode with load capacitance of 12 pF - 24 pF and frequency stability rating of ±100 PPM or better, it can't support 25MHz as it is outside of the hub requirement.
