USB hosts hubs transceivers Forum Discussions
I'm implementing a Data transfer Interface to bypass the proccessed data from a FPGA to the PC. I need high datarate and Power supply for FPGA and other parts connecting to the FPGA. As follows:
Data Transfer to PC: Sample Data -> FPGA -> USB -> PC
Flashing programs to the boards: PC -> USB -> FPGA/Other MCU
Power Supply: PC -> USB -> FPGA/Other Hardware
Any Ideas, recommendation or suggestion, which IC has to be Chosen?
Show LessCypress introduces its new low-cost single and multi-TT hubs.
Introducing the CY7C65632 (single TT) and CY7C65642multi TT) series of hubs. Both series are available in 2-port, 3-port and 4-port configurations.
Sampling from Q2 2011.
Contact your distributors for more information.

I’m looking for the robust cypress solution
for customer part selection of USB Hub controller which are designed with and figured out there are 2 parts : CY7C65632
(Single TT) and CY7C65642 (Multi TT(Transaction Translator)).
Do you have any comparision description like Benchingmarking test for both performances especiallly Single TT and Multi TT.
It’s not clear for me how fast CY7C65642 Multi-TT is than Single TT.
Best regards,
Wonjin Han.

Hi, I have been a long time user of Cypress Suite USB. I specifically used the Cypress Driver in my hardware devices. According to the Cypress online documentation, the Cypress drivers are only supported for no newer versions than windows 7. Seeing as Windows 7 has been discontinued, I now updated all my systems to Windows 10 and would like to know how Cypress can support my hardware. I am running Cypress Suite USB 3.4.7 on Windows 10 but drivers fail to install in my hardware devices.
Thank you for your time and consideration.

My customer wants to use cypress Hub solution to implement 1 Upstream & 30
Downstreem ports(USB 2.0) Hub and is wondering that is possible to do it in reality or not.
If you have any cypress robust solution, please give me your recommendation and how to implement it especially in Hardware.
Thank you and regards,
Wonjin Han.
Show LessStandard type-c interface with two pins SBU1 and SBU2? The USB 3.1 Gen 2 / Display Port 1.4 crossover switch for Type-C can be used for DP interface expansion, but I see the evaluation board of CYUSB4357. The SBU1 and SBU2 pins of the upstream type-c are not connected, and three downstream type- The SBU1 and SBU2 pins of c are also not connected. I want to use CYUSB4357 as a multifunctional docking station. One of the downstream type-c interfaces can be used to expand the DP bus. Can it be implemented? Are there other options? Thank you for your design.
Show LessHi,
I am using "CY7C65634-48AXC" part in my design. I have a doubt on the overcurrent protection. In the datasheet I can see this: "After detecting an overcurrent condition, hub reports overcurrent condition to the host and disables the PWR#
My doubt is How the HUB reports the overcurrent detection to HOST? Using USB packets??
Is there any driver files available for this HUB@ to work-out this overcurrent functionality in host. I am working in Linux.
Show LessHello,
I designed a board using the chip CY7C65215 based on the schematic shown in the datasheet. I didn't use the MCU, the Battery Charger and other peripherals as the datasheet said. When I connected the board to my PC via a USB cable, the PC cannot detect a new USB device, neighter the USB Serial Configuration Utility.
The schematic diagram is as below. Does it meet the minimum requirements for the chip to work? I had check the schematic and the PCB for a whole day, but I couldn't get any solution. Who can tell me if I miss somthing?
Thank you very much!

Please find attached.When they checked the rising waveform of the GANG pin, it dropped to the low level.However, since there is no problem with the rise of the 3.3V waveform , they are thinking that something has happened inside and the GANG input signal has dropped. Q) Could you please tell me the causes and mechanisms?
Best Regards
