DRA829J-Q1: PCIe Receiver Detection

Peter Fritzenschaft

Part Number: DRA829J-Q1

Tool/software:

Hello, 

we are using DRA829J-Q1 as PCIe Root Complex connected to an Artix UltraScale+ as Endpoint.

The UltraScale Datasheet states that dynamic switching of the receiver termination mode is required when the remote transmitter is using the falling edge for the receiver detection.

In the Jacinto documentation i cannot find something about the receiver detection edge.

Does the Jacinto use rising or falling edge for Receiver Detection?

Kind regards, Peter

    Peter,

    I am unsure if this is rising edge or falling edge receiver detection or if this is based on the signal level/ signal integrity reflected from the PHY.

    I will assign this to the PCIe expert from our team who will get back to you.
