Part Number: DS280MB810
In an application needing to support PCIe-like RX-detection, a 1V common-mode voltage square wave, AC-coupled and sourced via two 50 Ohm resistors, is applied to one of the DS280MB810 output differential pairs, as an artifact of attempting to detect the possible presence at the far end of the associated cable of a receiver, which if present will have a common-mode input impedance of 25 Ohms to ground.
Assuming the DS280MB810 output pair was being squelched (outputting 0V differential), please indicate whether the outputs would be expected to be able to handle without undue stress the resulting common-mode voltage, which could be as large as ~+/-0.55V in the case the far-end receiver is absent. If not, then please outline what magnitude of common-mode voltage could readily be tolerated.
