Intel Arria 10 User Manual

channels in the bank can be reconfigured as GX transceiver channels. However, when
any of the GT capable transceiver channels in transceiver banks GXBL1E, GXBL1G,
and GXBL1H is enabled as a GT transceiver channel, the remaining channels in the
transceiver bank cannot be used with the exception of the other GT capable channel in
the transceiver bank.
If you're using GT transceivers in bank GXBL1E, then the adjacent PCIe Hard IP block
cannot be used.

Notes:
(1) Nomenclature of left column bottom transceiver banks always end with “C”.
(2) Nomenclature of right column bottom transceiver banks may end with “C”, “D”, or “E”.
(3) If a GT channel is used in transceiver bank GXBL1E, the PCIe Hard IP adjacent to GXBL1F and GXBL1E cannot be used.

The GT device has 72 transceiver channels, which include 6 GT transceiver channels
supporting data rates greater than 17.4 Gbps. If all six GT transceiver channels are
used in GT mode, there are 54 GX transceiver channels that can drive chip to chip
data rates up to 17.4 Gbps and backplanes at data rates up to 12.5 Gbps and 12 GX
channels that are unusable.
In the GT device, the GX transceiver channels on the entire right side can be used in
standard or reduced power mode. In GT devices where none of the GT channels are
used to operate in GT data rates above 17.4 Gbps, the transceiver channels on either
the entire right side or entire left side can be used as GX channels in standard or
reduced power mode.
