Note: The core clock
frequencies listed in the table above are the minimum required to sustain the
bandwidth of the Interlaken interface based on the corresponding lane logic clock
frequency. Similarly, the AXI clock frequencies are the minimum required based on
the corresponding core clock frequency.
Note: The configurations indicating a maximum transceiver rate of 56.42 Gb/s
in the table above support frequency scaling by 2.800425% in faster devices to allow
support for a maximum transceiver rate of 58 Gb/s. Likewise, configurations listed
as 28.21 Gb/s support scaling to 29 Gb/s.
Note: Configurations for transceiver rates not listed
in the table are supported by frequency scaling of clocks. You can choose a valid
configuration row from the table and scale all frequencies (in that row) by the same
factor. The AXI4-Lite processor interface clock does not need to
be scaled.
Note: The TX and RX
Interlaken paths must be set to the same configuration.
