3.8. Analog Parameters

Through this tab, you can configure FHT and FGT PMAs settings. Intel recommends the following FHT and FGT PMAs settings for Intel Agilex® 7 I-Series Transceiver-SoC development kit:
Figure 19. FHT PMA SettingsThe recommended FHT PMA settings are shown below.
  • FHT TX
    • Enable FHT TX P&N Invert: Enabled
    • Select FHT TX Termination: TXTERM_OFFSET_M1(96.8 Ohms)
  • FHT RX
    • Enable FHT RX P&N Invert: Enabled
    • Select FHT RX Termination: RXTERM_OFFSET_P0(90 Ohms)
  • FHT PLL
    • Select FHT external AC Cap: EXTERNAL_AC_CAP_DISABLE
  • FHT TX EQ
    • Post-Cursor 2, 0.25 step size: -2.0
    • Post-Cursor 1, 0.5 step size: -2.0
    • Main-Cursor, 0.5 step size: 18.0
    • Pre-Cursor 1, 0.5 step size: -4.0
Figure 20. FGT PMA SettingsThe recommended FGT PMA settings are shown below.
Note: Depending on the data rate, use the following setting:
  1. For NRZ data rate of more than or equal to 23 Gbps or any PAM4 data rate, select VSR_MODE_LOW_LOSS.
  2. For NRZ data rate of less than 23 Gbps, select VSR_MODE_DISABLE.
When the NRZ data rate is less than 7 Gbps, Intel recommends to set the following parameters to use 0s.
  • RXEQ VGA Gain
  • RXEQ High Frequency Boost
  • RXEQ DFE Data Tap1
