I am operating PCIe over copper cables via re-drivers asynchronously. i.e. I only send over the RX/TX data.
The clock is sourced locally at the end point. For the host root port, I am designing a little PCIe add-in card that will have a PCIe re-driver.
For the add-in card I am wondering if I will need some sort of spread-spectrum clock squelching circuitry.
I am concerned that there will always be some hosts that will not let me turn off the spread-spectrum clocking.
Thank you in advance.
