PCIe Mode Configurations
Stratix IV GX and GT transceivers support both Gen1 (2.5 Gbps) and Gen2 (5 Gbps)
data rates in PCIe functional mode. When configured for the Gen2 (5 Gbps) data rate,
the Stratix IV GX and GT transceivers allow dynamic switching between Gen2
(5 Gbps) and Gen1 (2.5 Gbps) signaling rates. Dynamic switch capability between the
two PCIe signaling rates is critical for speed negotiation during link training.
Stratix IV GX and GT transceivers support ×1, ×4, and ×8 lane configurations in PCIe
functional mode at both 2.5 Gbps and 5 Gbps data rates. In PCIe ×1 configuration, the
PCS and PMA blocks of each channel are clocked and reset independently. PCIe ×4
and ×8 configurations support channel bonding for four-lane and eight-lane PCIe
links. In these bonded channel configurations, the PCS and PMA blocks of all bonded
channels share common clock and reset signals.
