The F-Tile Interlaken IP consists of two paths:
  • Interlaken TX path
  • Interlaken RX path
Each path includes MAC, PCS, and PMA blocks. The PCS blocks are implemented in hard IP. In the NRZ mode, the PCS is interfacing with the PMA directly. In the PAM4 mode, the PCS is interfacing with the Transcode and Alignment block.
