I am attempting to us the TS3L501E to switch between two Ethernet ports. My schematic is shown below.
If I use an ohm meter to test the switching function, it seems to work fine. A few ohms when it is switched on and a few megaohms when off. The resistance between the pins, on the same connector is around 2M. However, when I tested with a cable tester it shows that some of the signals are open and that some are crossed. Is it possible the chip was injured by the hot air soldering. or is this crosstalk or something else? I have routed the airs together with 7mil spacing, and ave put at least 50mils between pairs.
