  • Gen1 (2.5 GT/s), Gen2 (5.0 GT/s), Gen3 (8.0 GT/s), and Gen4 (16 GT/s) speeds are supported.
  • UltraScale devices support 2.5 GT/s, 5.0 GT/s, and 8.0 GT/s line rates with x1, x2, x4, x8 lane operation.
  • UltraScale+ devices support 2.5 GT/s, 5.0 GT/s, and 8.0 GT/s line rates with x1, x2, x4, x8, x16 lane operation. Additionally, they support 16.0 GT/s line rate with x1, x2, x4, x8 lane operation.
  • Supports P0s low power state when configured as Gen1 or Gen2 only.
  • Supports synchronous and asynchronous applications.
  • Rate change between Gen1 and Gen2 is a fixed datapath implementation.
  • Rate change between Gen3 and Gen4 is a fixed PCLK implementation.
  • Low latency enabled by bypassing TX buffer.
  • Equalization sequence is part of the GT Quad in Versal devices provided Xilinx MAC is used. For any third party MAC still the equalization is part of the PHY IP.
