    +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)

    + * 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)
