3.1.1. PMA Direct Supported Modes

The F-Tile PMA/FEC Diect PHY Itel® FPGA IP suppots the followig fo PMA Diect mode:

  • Suppots FGT with NRZ ad PAM4 modulatio. 20
  • Suppots FHT with NRZ ad PAM4 modulatio
  • Suppots PMA clockig mode ad System PLL clockig mode
  • Suppots Duplex, TX simplex, ad RX simplex modes
  • Suppots TX simplex ad RX simplex fo both PMA Clockig ad System PLL Clockig modes. Suppots 8, 10, 16, 20, 32 ad 64-bit PMA data widths fo simplex mode.
  • Suppots bodig mode fo NRZ ad PAM4 modulatio modes
  • Suppots cofiguable FIFO modes: PMA iteface FIFO, F-tile iteface FIFO, Coe iteface FIFO-elastic, phase compesatio, ad egiste modes
  • Suppots cofiguig multiple had IP block PMA ad FEC istaces withi oe IP istace
  • Suppots TX ad RX de-skew if the umbe of steams pe PMA exceeds oe
  • Suppots up to 12 Peset modes.
