Part Number: TS3L4892
I am using ts3l4892 and I am having a problem getting a 100b link. Tester is reporting an unterminated issue, has anyone seen this issue

Please see block diagram.
In reply to Martin Corona:
The TS3L4892 device recommended operating conditions states the voltage range is 0 V to Vcc. The switch will not pass signals < 0V and is why you are seeing clipping when the voltages reach ~ -0.5 V on the signal path.
All of our LAN switches have minimum recommended operating voltages of 0V and will have this issue so you will need to provide a common mode voltage.
As far as the signal switch is concerned the only recommendation we have is the signal voltage needs to be > 0V. The transformer recommendation would need to come from the transmitter or receive. I don't have anything from a switch perspective.
Would this be the best configuration for the TS3L4892? Two Ethernet Magnetic Transformers on PCB1, PCB2 is of the shelf and has its own Ethernet transformers. Please let me know.
The TS3L4892 does not have a spec that guarantees isolation like the TS3L501E where it states HiZ when Vdd = 0V and I/O voltage = 3.6 V. We cannot recommended operating the TS3L4892 without power and voltages on the I/O pins.
