More information and documentation on solutions using the integrated interface block for Interlaken can be found at UltraScale+ Interlaken . The UltraScale Architecture and Product Data Sheet: Overview (DS890) lists how many blocks are in each Zynq UltraScale+ RFSoC. This section describes the following Interlaken configurations.

  • 12 x 12.5 Gb/s protocol and lane logic mode (Table 1) .
  • 6 x 25.78125 Gb/s and 6 x 28.21 Gb/s protocol and lane logic mode (Table 2) .
  • 12 x 25.78125 Gb/s lane logic only mode (Table 3) .
