4.9. Stratix V GT Device Configurations

Stratix V GT devices contain both 28.05 Gbps GT transceivers and 12.5 Gbps GX transceivers. The GT transceivers can be configured only in PMA-Direct configuration using the Low Latency PHY IP. The GT channels have serial data rates that range from 19.6 Gbps to 28.05 Gbps.

To implement a Low Latency PHY link with the GT channel, instantiate the Low Latency PHY IP core in the IP Catalog, under Transceiver PHY in the Interfaces menu. In the Low Latency GUI under the General tab, select GT on the Datapath type selection.
