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 = 700 mV for Arria V GX and SX in PCIe mode only. e AC coupled VICM = 750 mV for Arria V GT and ST in 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.
tLTD_manual is the time required for the receiver CDR to start recovering valid data afer the rx_is_lockedtodatasignal goes high when the CDR is
functioning in the manual mode.
tLTR_LTD_manual is the time the receiver CDR must be kept in lock to reference (LTR) mode afer the rx_is_lockedtorefsignal goes high when the
CDR is functioning in the manual mode.
