Table 6. PCS Types Supported by GX Transceiver Channels
PCS Type Data Rate
Standard PCS 1.0 Gbps to 10.81344 Gbps
Enhanced PCS 1.0 Gbps
(6)
to 17.4 Gbps
PCIe Gen3 PCS 8 Gbps
Note: 1. The GX channel can also operate in PCS Direct configuration for data rates from
1.0 Gbps to 17.4 Gbps. To operate GX transceiver channels in PCS Direct
designated data rates, refer to the IntelArria 10 Device Datasheet for more details
on power supply, speed grade, and transceiver configurations requirement.
2. The minimum operational data rate is 1.0 Gbps for both the transmitter and
receiver. For transmitter data rates less than 1.0 Gbps, oversampling must be
applied at the transmitter. For receiver data rates less than 1.0 Gbps,
oversampling must be applied at the receiver.
3. To operate GX transceiver channels with the PCS at designated data rates, refer to
the IntelArria 10 Device Datasheet for more details on power supply, speed grade,
and transceiver configurations requirement.

1.2.2.2. The GT Transceiver Channel
The GT transceiver channels are used for supporting data rates from 17.4 Gbps to
25.8 Gbps. The PCS Direct datapath that bypasses all PCS blocks is the primary
configuration used to support GT data rates from 17.4 Gbps to 25.8 Gbps.
Alternatively, the Enhanced PCS in Basic low latency configuration can also be used to
support GT data rates from 17.4 Gbps to 25.8 Gbps. The GT transceiver channels can
also be configured as GX transceiver channels. When they are configured as GX
transceiver channels, the Standard PCS, Enhanced PCS, and PCIe Gen3 PCS are
available and they support data rates from 1.0 Gbps to 17.4 Gbps.

Applies when operating in reduced power modes. For standard power modes, the Enhanced
PCS minimum data rate is 1600 Mbps.
