description: |
  The Sparx5 SERDES interfaces share the same basic functionality, but
  support different operating modes and line rates.

  The following list lists the SERDES features:

  * RX Adaptive Decision Feedback Equalizer (DFE)
  * Programmable continuous time linear equalizer (CTLE)
  * Rx variable gain control
  * Rx built-in fault detector (loss-of-lock/loss-of-signal)
  * Adjustable tx de-emphasis (FFE)
  * Tx output amplitude control
  * Supports rx eye monitor
  * Multiple loopback modes
  * Prbs generator and checker
  * Polarity inversion control

  SERDES6G:

  The SERDES6G is a high-speed SERDES interface, which can operate at
  the following data rates:

  * 100 Mbps (100BASE-FX)
  * 1.25 Gbps (SGMII/1000BASE-X/1000BASE-KX)
  * 3.125 Gbps (2.5GBASE-X/2.5GBASE-KX)
  * 5.15625 Gbps (5GBASE-KR/5G-USXGMII)

  SERDES10G

  The SERDES10G is a high-speed SERDES interface, which can operate at
  the following data rates:

  * 100 Mbps (100BASE-FX)
  * 1.25 Gbps (SGMII/1000BASE-X/1000BASE-KX)
  * 3.125 Gbps (2.5GBASE-X/2.5GBASE-KX)
  * 5 Gbps (QSGMII/USGMII)
  * 5.15625 Gbps (5GBASE-KR/5G-USXGMII)
  * 10 Gbps (10G-USGMII)
  * 10.3125 Gbps (10GBASE-R/10GBASE-KR/USXGMII)

  SERDES25G

  The SERDES25G is a high-speed SERDES interface, which can operate at
  the following data rates:

  * 1.25 Gbps (SGMII/1000BASE-X/1000BASE-KX)
  * 3.125 Gbps (2.5GBASE-X/2.5GBASE-KX)
  * 5 Gbps (QSGMII/USGMII)
  * 5.15625 Gbps (5GBASE-KR/5G-USXGMII)
  * 10 Gbps (10G-USGMII)
  * 10.3125 Gbps (10GBASE-R/10GBASE-KR/USXGMII)
  * 25.78125 Gbps (25GBASE-KR/25GBASE-CR/25GBASE-SR/25GBASE-LR/25GBASE-ER)

  lan969x has ten SERDES10G interfaces that share the same features, operating
  modes and data rates as the equivalent Sparx5 SERDES10G interfaces.
