Hi all,
I have a question on using switches on differential lines.
An ethernet design is done for NIC (MDI) application. There are 2 pairs =
(1 Tx & 1 RX) of differential lines which on which signal speed is =
100Mbps.
Now we are thinking of giving MDIX option too so that both straight and =
cross cable can be used. For that we don't want to disturb the design =
except providing switches between magnetics and port to select differential=
lines.
Also i have to ensure that there is no cross routing of transmit and =
receive signals.
Even after that will there be any signal integrity issues? Has anybody =
done this kind of design or do u know any product having switch option to =
select b/w MDI & MDIX?
Pls help.
Thanks
GowdaBPS
