Where is the field/setting in the HX3 Blaster Tool to configure using external clock as per AN91378 "HX3 Hardware Design Guidelines and Schematic Checklist" ?

AN91378 "HX3 Hardware Design Guidelines and Schematic Checklist": 

"External Clock Input Requirements

HX3 operates with the external clock input as well. HX3 needs to be configured to use the external clock input and this can be done using Cypress Blaster Plus tool. Blaster Plus is a GUI-based tool to configure HX3."

Hi. Infineon

In former case Solved: Solved: USB3.0 HUB CYUSB3314-88LTXC read register - Infineon Developer Community;customer still find the PC can't identify  USB3.0 U disk status, but it may identify the USB2.0 U device in downstream  with CYUSB3314-88LTXC, they  consider the HUB go to eSS.disable staus, how to solve it. At the same time,their schematic design without external E2PROM, I also let them add the circuit to test whether it is the same issue.(USB3.0设备无法识别，但是USB2.0可以正常识别，怀疑接入的U盘进入了eSS.Disabled模式导致hub的下行口无法使用，如是这情况，该如何解决，同时，设计原理图中无外挂E2PROM，建议增加这块电路进一步验证和测试。)

thanks

Are there any requirements when powering up HX2VL?

I would like to know if there are any conditions such as ramp rate or monotonic increase required.

Thanks,

The customer would like to know how to let hx3 enter test mode for eye pattern test.

They said they finished usb3.0 eye pattern test, but hx3 can't enter test mode when hx3 run at usb2.0 

They want to know how to enter test mode in USB2.0?

Hi Infineon team,

We Teksun Inc are currently working on a product where we used the CYUSB331x HX3 USB 3.0 Hub.  He re as a vendor, we required the Vendor-Command support to programming/configure the controller to work as standalone USB hub. for the purpose, we required the document and tool support from your side to fulfill our requirement.  

Kindly let me know if you required anything from my side. Attaching the datasheet of our part that we are using.

Waiting for your reply.

I can transfer data with MCU directly.

But when I use CY7C65642(MCU1 connect to D2+/D2-,MCU connect to D3+/D3-,PC connect to D1+/D1-), I cannot open the USB device(MCU).

There is a description of the Cin (Input pin capacitance) parameter in the datasheet.

Is the meaning of this parameter the capacitance that the USB HUB's input pin itself has? Or is it the value that limits the capacitance of the signal coming into the input pins of the USB HUB?

Also, Cin of HX2LP is 10pF. And according to the USB2.0 specification document (Section 7.1.6.2), the capacitance is to allow no more than 5.0 pF for the Die and no more than an additional 5 pF for the Package.

The sum is 10pF, but is it correct to understand that this satisfies Cin's 10pF?

Thanks,
Tetsuo

Hi,

We are designing a docking station which is capable of automatically disabling and enabling the ACA docking in runtime. Can you please suggest the circuit design for the same.

Thanks
