128B/130B is an industry standard encoding scheme, and protocols like PCI Express® use 128B/130B encoding on outgoing data when a PCI Express link is operating at a data rate of 8.0 GT/s or higher. The GTY/GTYP transceiver has a built-in 128B/130B TX path to encode TX data without consuming device resources. Support for the 128B/130B encoder in Versal adaptive SoC GTY/GTYP transceivers is only available through the PCIe PHY IP.
