USB superspeed peripherals Forum Discussions

I am currently trying to get the openocd debugger to work on windows 11 on the superspeed explorer devkit, and i've followed what the guide showed, but i'm getting some halt related errors:

it never goes into my breakpoints (which are on the main function) and terminates the process.

The required devices are indeed visible in the usb control center:

Any idea on what i might've missed? I've followed this guide:
https://www.infineon.com/dgdl/Infineon-SuperSpeed_Explorer_Kit_User_Guide-UserManual-v01_00-EN.pdf

We' ve been studying "Infineon-AN70707_EZ-USB_FX3_FX3S_SX3_hardware_design_guidelines_and_schematic_checklist-ApplicationNotes-v18_00-EN.pdf" for our PCB design but there is some confusion about some of the recommendations.

1) First of all the track width for the superspeed signals. On page 26/table 10 it is stated that according to USB spec the trace width should be 11 mils (and intra pair spacing 8 mils). Below the table there's a comment saying this can be ignored when the characteristic impedance is 90 Ohms. The 90 Ohms makes sense but we don't understand why it can also be 11 mils as this will yield an impedance mismatch in a variety of cases causing reflections/signal integrity problems. We've also studied the PCB of the "SuperSpeed Explorer Kit Layout", where 6.5 mil traces are used with a ~13.5 mil gap (aka intra pair spacing). But according to our calculations this would yield a differential impedance of ~128 Ohms. So again, why did you deviate from both the 90 Ohm differential impedance AND the 11 mil / 8 mil spacing in AN70707? So what's the best advice keeping all of the above in mind?

2) There's a recommendation to not use VIAs on the XTAL IN/OUT and superspeed traces but the "SuperSpeed Explorer Kit Layout" doesn't follow this recommendation. Why?

3) With super speed signals, when switching layers, a ground VIA should be placed at at least 40 mil distance (page 25, figure 25). But we interpret "at least" as it could also be 80, 800 mil or some other insanely large value. I assume you mean: it should be at least 40 mil but above 40 mil it should be as close as possible to 40 mil, right?

4) There's no VIA size recommendation for super speed signals in AN70707. According to a colleague of mine it's best to use  a VIA with the smallest outer diameter as possible, with the biggest drill possible (available at the PCB manufacturer).  Again this isn't the case in the "SuperSpeed Explorer Kit Layout" since the VIAs used there for the superspeed signals are larger than the ones used for the BGA fanout. Any recommendations?

这个对话框怎么打开，谢谢！

Hi Sir/Mam, 

We wish to do configuration for FX3 board with our FPGA which is giving video stream at resolution 3264 * 2448 (active resolution) and 2560 * 1440 (active resolution). 

I have previously implemented the design for 1920 * 1080 @ 60 fps by taking reference of application note AN75779, but now I want to check compatibility with higher resolutions as mentioned above. I have few questions regarding that - 

1. Is FX3 board compatible to stream video data at 2k and 4k resolution?

2. What is the maximum frame rate at which I can stream video data?

3. what is the maximum resolution supported by the board?

4. How to calculate DMA buffer size for changed resolution and frame rate?

Please guide me for the above questions.

 Thanks & Regards, 

Akash

Hello,

I see SX3 Utility FPGA Configuration has only 4 types of FPGA:

Lattice Crosslink

Xilinx Artix 7

Intel (Altera) Cyclone 10 LP

Lattice ECP5 

Does it support another types of FPGA? Microchip PolarFire FPGA, for example: MPF300TL-FCSG536I

Thanks,

Michael
