Part Number: HD3SS3220 Tool/software: Hi,
I am considering a circuit configuration to use HD3SS3220 in UFP mode.
Q1. When using in UFP mode, am I correct in thinking that the TX pin of the USB multiplexer and the TX pin of the USB Type-C connector are…
Part Number: HD3SS3220 Tool/software: In the Document 'HD3SS DFP Dongle Evaluation Module ' The USB SS TX pins of the HD3SS3220 is connected to the RX pin of the Host and the Same for the USB-C connecteor at output .
This is not the case in the…

Part Number: TUSB1002 Other Parts Discussed in Thread: , HD3SS3220 Tool/software: Hi,
I am using the TUSB1002 and the HD3SS3220 in a SuperSpeedPlus (10Gbps) application which connects an FPGA via the TUSB1002 and HD3SS3220 to a USB C connector. The attached…
Part Number: HD3SS3220 Tool/software: We typically add 0.1µF series capacitors for the USB SS lines but in the UFP EVM schematic, it list 0.5µF capacitors. What is the reasoning behind the 0.5µF value and is there any downside to using 0.1µF capacitors…
Part Number: HD3SS3220 Hi Team,
Customer is using HD3SS3220 in their design as DFP, but they found the the ID pin for HD3SS3220 can not work to low or high output when type-C U-disk inserted during test, can you help to check customer's schematic as below…
Hi Ryan,
Thanks for your feedback. Another question, When my customer is setting UFP and could they use I2C to read the current maximum current provided by the host right?
Because they found out at the datasheet, there is a register that can read the…
Part Number: HD3SS3220 Tool/software: Hi,
Our customer is planning to connect two resistors in series to V(BUS) to configure 900k ohms. Is there any problem with that?
Best regards,

Part Number: HD3SS3220 Tool/software: Hi,
The following image shows how we are connecting an FPGA to the HD3SS3220 mux and then to a USB C connector. Could you let me know if the AC decoupling caps are correct. They are all 0.1uf.
Thank you
Liam
Part Number: HD3SS3220 Tool/software: Hello,
My customer encountered an issue where USB disconnection was not recognized on the board developed using the HD3SS3220.
When connecting to a laptop with a C to C cable and then removing the USB connection…
