Hi.
I have a single RJ45 connector, that connects to an external device, that can use it either as a single 1000BaseT port, or two 100BaseT 'ports'. I've chosen the TS3L501E device to perform the required switching.
I need to multiplex these signals to two further RJ45 connectors, depending on the format being used by the external device, as follows:
a. 1000BaseT - port A of TS3L501E connects to port C of TS3L501E, and then onwards to one RJ45 connector.
b. 100BaseT - port A of TS3L501E connects to port B of TS3L501E, then B0-B3 is routed to one RJ45 connector, and B4-B7 are routed to the same RJ45 connector that is used in a. above. This requires that B0-B3 are effectively connected to 4 of the C port pins on the TS3L501E. Obviously, only one of port B & C are 'active' at any one time.
If the stubs connecting the B pins and C pins are kept as short as possible (and the same length), do you see a problem with this setup? I've uploaded my proposed schematic for clarity - please advise if you see any issues with the schematic, irrespective of my prime question above.
Thank you.
