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 Virtex UltraScale+ FPGA. 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) .

Virtex UltraScale+ FPGAs in the FLGF1924 package are only supported using the 12 x 12.5 Gb/s Interlaken configuration. See the FGTYMAX maximum line rates.

  1. 6 x 28.21 mode is only supported in the -2 (VCCINT = 0.85V) and -3 (VCCINT = 0.90V) speed grades.
  2. These are the minimum clock frequencies at the maximum lane performance.
  3. The minimum value for CORE_CLK is 451.36 MHz for the 6 x 28.21 Gb/s protocol.
  4. The minimum value for LBUS_CLK is 330.00 MHz for the 6 x 28.21 Gb/s protocol.
