5.0 DP83858 Applications
5.1 MII Interface Connections
The DP83858 can be interfaced with the DP83840A in the
same fashion as the DP83850 as described in the Applica-
tion Note 1069 "100BASE-TX Unmanaged Repeater
Design Recommendations". Designers should be aware
that there are significant issues involved in the signal tim-
ing, loading and layout of this interface and they should
consult this Application Note and/or their National Semi-
conductor representative prior to attempting a design. Fur-
ther system timing analysis shows that the RXD[3:0],
RX_DV and RX_ER signals should be latched into the
DP83858 from the connected DP83840As. Figure 5 shows
the recommended scheme. This ensures system timing
can be met for hub stacks.
