USB interface for FPGA

koka_4806451 · ‎Oct 26, 2020

Hello.

We are looking for a way to add USB interface on an FPGA board to connect the board to a commercial USB3.0 camera directly.

Could you tell me if EZ-USB FX3 controller is the best solution for our purpose?

Thank you

Hello,

In this scenario the FX3 is expected to act as a host and send the data received from camera (USB interface) to FPGA (through parallel interface).

Please correct me if my understanding is wrong.

Fx3 can act as a high speed host (USB 2.0) and not a super speed host (USB 3.0).

If the application needs camera to work as a 3.0 device (with SS phy, speed of 5Gbps) then FX3 cannot be used in this application.

In the other case, if the camera is working in 2.0 speeds (using 2.0 phy, speed 480Mbps), then FX3 can be used in for your application mentioned.

Thanks,

Yatheesh
