+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)
