USB hosts hubs transceivers Forum Discussions
Hello there,
I would like to understand the feasibility of using multiple HX3PDs to create a hub with more than three 10Gbps TypeC ports on a single host.
Let's start with the reference design -- a single HX3PD with the following DS ports:
- 1x 3.1-Gen2-TypeC-PD3.0 (DS1)
- 2x 3.1-Gen2-TypeC-noPD (DS2, DS3)
- 2x 3.1-Gen2-TypeA (DS4, DS5)
- 2x 2.0-TypeA (ignore these)
So in this single-board HX3PD#1 configuration, I have 3 TypeC DFP ports (DS1-DS3).
Is this correct so far?
Now, let's say I have two of these reference design boards (HX3PD#1, HX3PD#2).
How can I wire the two boards together to achieve the most TypeC ports?
Here are a few scenarios I can think of:
1) Can I connect HX3PD#2-US port to either HX3PD#1-DS4 or -DS5 and still have full TypeC bandwidth on each port on HX3PD#2?
----> Result: 6x TypeC ports -- HX3PD#1 DS1/DS2/DS3, HX3PD#2 DS1/DS2/DS3, 2 of which are PD-capable.
2) Furthermore, can I reconfigure the firmware to move HX3PD#2 Upstream port to be on one of the TypeA ports (DS4,DS5), therefore freeing up HX3PD#2-US port as a DFP-PD port?
----> Result: 7x TypeC ports -- HX3PD#1 DS1/DS2/DS3, HX3PD#2 US/DS1/DS2/DS3, 3 of which are PD-capable.
3) Or, do I NEED to connect TypeC-to-TypeC?
----> Result: 5x TypeC ports -- HX3PD#1 DS1/DS3, HX3PD#2 DS1/DS2/DS3, 2 of which are PD-capable.
4) Or even worse, do I need to connect TypeC-PD-to-TypeC-PD?
----> Result: 5x TypeC ports -- HX3PD#1 DS2/DS3, HX3PD#2 DS1/DS2/DS3, only 1 of which is PD-capable.
Are there any other configurations that make more sense?
Any thoughts are greatly appreciated.
Thanks in advance,

Show LessHello Team,
We are trying to configure HX3C USB Hub. Earlier device is detecting but it is showing as Unknown device. But at present it is not detecting at all. Attached schematics, hardware setup for your reference.
In schematics we used pogo pins (J92, J109, J110, J111, J112, J113, J114) to interconnect the mother card and daughter card of USB Type C receptacle.
With 3.0 USB Type c there is no positive result. Trying from past few months. Still can't able to achieve. Kindly suggest possible solution to overcome this problem.
If we go with 2.0 USB micro B. Can we achieve our configuration. If yes, kindly suggest how to configure HX3C using usb 2.0.

Hello
I have a question about CY7C65632-48AXC.
There is description below in the "Operating Conditions (page 19)" of HX2LV datasheet.
https://www.cypress.com/file/114101/download
「5 V supply voltage to ground potential ......4.75 V to +5.25 V」
While, there is description below in the "7.2.2 Voltage Drop Budget(page 175)" of the USB 2.0 specification.
「The voltage supplied by low-powered hub ports is 4.4 V to 5.25 V.」
If the voltage drop is the worst, can HX2LV not keep with this USB 2.0 specification?
Best Regards
Show LessPlease provide CYUSB2302-BVXA datasheet for auto application.
Hi Sir,
I can't search CYUSB2302 automotive grade reference schematic form Cypress website. Please provide it.
Thanks a lot !!!
Best Regards.
