Does ATX PLL support Spread spectrum Clocking?

I am using S-10 SoC Dev kit for some Proof of concept execution which includes XCVR native PHY configured @20Gbps datarate. I want to know whethe ATX PLL supports SSC (Spread spectrum clocking) of downspread rate 30-33KHz and downspread range of 0.4-0.5%?

I am planning to feed the downspread clock from an Programmable oscillator which supports SSC.

 

With Regards,

Hi HPB, As I understand it, you have some inquiries related to the spread spectrum clocking in S10 SX devices. I believe you are For your information, SSC is supported for PCIe mode only in the S10 SX devices. It is not supported for other XCVR mode. You may refer to the S10 device datasheet L- or H-Tile Reference Clock Specifications section for further details. Sorry for the inconvenience. Please let me know if there is any concern. Thank you. Best regards, Chee Pin
