DP83867IR: GMII to MDI Latency

Part Number: DP83867IR

Hi team,

It seems that T6 should be applied to only the first frame after power-on accoding to figure 6. Is this right?

And how should they take care about the GMII to MDI Latency when they design the system?

Regards,

Noriyuki Takahashi

  • Hi,

    Even though T6 is shown in the timing diagram as the delay between edge of GTX_CLK and First Frame, the same delay is the latency between GMII to MDI.
    The latency is 72ns(typ) in 1000Base-T mode.

    Please let me know if you need more details regarding this.
