5.2.1.3. Interlaken Frame Generator

The Interlaken frame generator block takes the data from the TX PCS FIFO and encapsulates the payload and burst/idle control words from the FPGA fabric with the framing layer’s control words (synchronization word, scrambler state word, skip word, and diagnostic word) to form a metaframe. The Native PHY IP core allows you to set the metaframe length from five 8-byte words to a maximum value of 8192 (64Kbyte words).

Use the same value on frame generator metaframe length for the transmitter and receiver.
