DP83849I: RX_ER detection time

Koshi Ninomiya

Part Number: DP83849I

Hi Team,

Could you let me know about detection time from transmission error occurred to RX_ER output of DP83849I?
Thank you.

Hi Koshi-san,

RX_ER indicates the errors in received packet. The delay in singalling will be inline with recieve path latency delay.

Hi Geet-san,

About the receive path latency delay, which AC timing specification should we refer?

100 Mb/s MII RECEIVE TIMING (REFER TO Figure 4-5)
T2.5.2 : RX_CLK to RXD[3:0], RX_DV, RX_ER Delay : 100 Mb/s Normal mode : Min=10 ns, Max=30 ns

100BASE-TX RECEIVE PACKET LATENCY TIMING (REFER TO Figure 4-9)
T2.9.2 : Receive Data Latency : 100 Mb/s Normal mode : Typ=24 bits

or others?

Best Regards,

HI Koshi-san,

For Recieve Path latency, we shall look for Figure 4.9. T2.9.2.
