Part Number: HD3SS3220 Hi,
I am using HD3SS3220IRNHT mux in my design and since I am using this part for the first time, need review support.
Attaching the Block diagram of my Board and the Schematic page which has HD3SS3220IRNHT .
FYI: the Type-C USB port…
Part Number: HD3SS3220 As shown in the figure below, we have designed HD3SS3220IRNHR to reserve both GPIO mode and I2C mode. Please help check if the circuit is correct in both modes, as our host's GPIO voltage threshold is 1.8V, and we have reserved…
Part Number: HD3SS3220 Hi team,
my customer try to use a LDO convert VDD5V to VCC33, so he wants to know the maximum power consumption of VCC33
but I only found this power consumption table,
is this total consumption of both 3.3v and 5V or only for VDD5V…

Could you please review attached schematics and provide feedback?
Please have a close look at
- SSRX/SSTX from USB-B 3.0 through…
Hi Kei,
Looking at the schematic I don't see AC coupling capacitors or biasing circuits on your high speed signal traces. Can you double check that the common mode voltage is within 0V - 2V?
Here is the biasing circuit on the 3220 DFP EVM , you can…
Hi Huang,
Huang Bang said: I still have some pcb wiring problems, do I need to open a single post for similar pcb problems? Because I noticed that the questions I was asking were drifting away from the title.
Its ok to ask any questions related to your…
