How to implement LFPS in Cyclone 10 GX transceiver IP

Hi, I am gonna design a USB3.0 port by using the Cyclone 10GX transceiver IP. In USB3.0/3.1 it needs to send a side band signal, Low frequency Period Signal(LFPS) to other partners . Is there anyone...

Hi Farabi,
Thank you for your response.
But, from the block diagram of TUSB1002 (@page14) it only shows that it only can detect LFPS at RX ports while doesn’t mention how to generate LFPS at TX ports.
Please advise further. Very appreciated!

Hi,
according to my knowledge, Agilex 7 F-Tile PHY implements the first and only LFPS detector available with Intel FPGA. Apparently no dedicated LFPS generator. Presume it has to be implemented by oversampling, should work for Cyclone 10 GX too.
