I would like to build a USB 3.0 PHY with FPGA. I have heard that some FPGAs transcievers should support OOB that is used in USB SuperSpeed differential lines. I am also wondering if such devices exist in ball-less package (I would like my device to use 2 layer PCB).
I am aware of FX3 devices from Cypress and PHY from Texas Instruments but they are both BGA devices.
