7.4. F-Tile TX Equalizer Tool

A high-speed signal traveling through a backplane is subject to high-frequency losses, primarily skin effect and dielectric losses. These losses can severely degrade and attenuate the high-frequency content of the signal, making it difficult for the receiver to interpret the signal. The F-Tile FGT TX PMA offers pre-emphasis and linear equalization to address this problem and improve the high-speed signal quality.

You can use the F-Tile TX Equalizer Tool to estimate the pre-emphasis and output swing. The tool displays the FGT PMA transmitter output swing when you change transmitter’s:
  • Main_tap
  • Post_tap_1
  • Pre_tap_1
  • Pre_tap_2
