USB-REDRIVER-EVM: Cascading multiple Redrivers to achieve longer USB3 cable length

Hi,

I am having a difficult time extending my usb3.0 cable length in the system.

Here is a block diagram of the system:

In this configuration the USB port is reading USB 2.1 .

I am trying to achieve around 7-8m of cable length total.

I tried to configure the EQ, OS, DE pins, but still getting the same result.

This is the first time I am using a Redriver, so any help would be appreciated.

Thanks.
