TUSB7340 termination question

Other Parts Discussed in Thread: TUSB7340

Hello all,

I'm trying to find out for a customer if there is a DC-bias inside the TUSB7340 (50 Ohm termination to the DC-bias) per PCIe standard?

The TUSB7340 datasheet states that the minimum RX input voltage is 0V. It means the incoming RX signal must have a DC component in it.

Regards,
Mateo

Mateo,

I'm going to move this to the Consumer and Computing forum where these parts are supported.

Thank you,
Adam

Hello,
Yes, the TUSB7340 has DC bias on its PCIE_TX pins.
I will review the datasheet with the Design team.
