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)
