e device cannot tolerate prolonged operation at this absolute maximum.
(46)
e differential eye opening specification at the receiver input pins assumes that you have disabled the Receiver Equalization feature. If you enable
the Receiver Equalization feature, the receiver circuitry can tolerate a lower minimum eye opening, depending on the equalization level.
e AC coupled VICM is 750 mV for PCIe mode only.

For standard protocol compliance, use AC coupling.
tLTR is the time required for the receive CDR to lock to the input reference clock frequency afer coming out of reset.
tLTD is time required for the receiver CDR to start recovering valid data afer the rx_is_lockedtodatasignal goes high.
