7.2. 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 Agilex™ 5 FPGA transmitter PMA offers pre-emphasis and linear equalization to address this problem and improve the high-speed signal quality.

You can use the GTS Transceiver TX Equalization Tool to estimate the pre-emphasis and output swing. The tool displays the Agilex™ 5 FPGA transmitter PMA output swing when you change the transmitter’s:
  • Main_tap
  • Post_tap_1
  • Pre_tap_1
  • Pre_tap_2
The Excel-based Agilex™ 5 FPGA GTS Transceiver TX Equalization Tool is available for download at GTS Transceiver TX Equalization Tool . A screenshot of the tool is shown in the following figure.
