TDP2004: Termination, Standby Mode, Impedance

Nikita

1. Termination.

There is mention that TDP has 100 Ohm termination, but I could not find how exactly termination is connected. If it is connected to some Vbais source, what is the level of the Vbais?

The RX is biased to 1.4V while the TX is biased to 1.0V,

2. Standby Mode, Impedance

I can see impedances are defined for the Stand-By Mode of TDP2044 (DP Redriver for USB Type-C), TDP2044 is in HI-Z state when PD = H. What about TDP2004?

Where do you see this info?

Thanks

David

1. Ok, I see, thanks.

2. >>> Where do you see this info?

"Table 7-3. TX and RX Pins in Standby Mode" of 2044's datasheet, probably "hi-z" is not the best name for this case, but what are the characteristics in standby mode for TDP2004?

In standby mode the (when PD = H) the RX impedance is High-Z. I'm looking into the TX characteristics.

Hi Pithadiya, I guess I don't need more detail regarding TX termination, David's answer closed my question, thank you.

Good to know, thank you! I'll wait for any updates TX  characteristics. I am interested in that because according DP spec there might be a situation when DP device can be in a disable mode, and DP spec defines some states for this mode.
